Kate Middleton Pregnant

Michael Christian and Mel Greig -- the two Australian radio DJs behind the Kate Middleton hospital prank call that led to the suicide of a nurse -- say they are "incredibly sorry" for what transpired ... as they speak out for the first time.

The pair sat down with "A Current Affair" in Australia and described how they found out that Jacintha Saldanha had taken her life. Michael said they got the news at the same time and Mel called it "the worst phone call I've ever had in my life."

The DJs have been off the air since the incident, which they say has weighed on them ever since. Mel explained, "There’s not a minute that goes by that we don’t think about the family and what they must be going through and the thought we might have played a part in that is discouraging ... I wanted to just to reach out to them and give them a hug and say sorry, I actually do feel sorry, I really do."

The Australian DJ who pretended to be Queen Elizabeth II in a prank phone call ... BRAGGED about her accomplishment on Facebook ... right before the nurse who answered the call committed suicide.

TMZ obtained a screenshot of Mel Greig's Fbook page taken Friday evening in Australia ... a.k.a. BEFORE news broke that Jacintha Saldanha -- the nurse duped by Greig and her co-host -- had been found dead in London.

The post reads ... "Why is it that I can impersonate the queen to get private royal information but no one believes I'm the queen for a free champagne whilst out?"

Greig attached a pic to the post -- of herself and another chick, smiling and hanging out at a bar.

We reached out to Mel's rep for comment ... who said (again), "No one could have ever predicted the tragic sequence of events that followed the prank call."

As TMZ previously reported ... Greig and her co-host Michael Christian shut down their Facebook and Twitter pages immediately after the nurse's death -- and suspended their gig at the station.

Lexus Australia has axed all of their advertising from 2DAYFM ... the radio station that allowed two DJs to prank call Kate Middleton's hospital ... TMZ has learned.

TMZ spoke to a rep for Lexus AU ... who tells us the company has officially pulled the plug on their media campaign due to "the current situation​" -- specifically the suspected suicide of the nurse who answered the call.

We're told this isn't the first time Lexus AU has pulled ads from 2DAYFM. The car company pulled ads from the station last year as well following an incident with a different announcer.

Finally putting a face to name, the first photo of the nurse from Kate Middleton's hospital who committed suicide hours after two Australian DJ's pranked her has just been released.

Scotland Yard sent out the haunting snap-shot of Jacintha Saldanha -- the nurse on-call at King Edward VII Hospital in London -- who was duped by two radio DJs pretending to be the Queen of England and Prince Charles.

According to Scotland Yard, the 46-year-old Saldanha was pronounced dead on scene Friday and her death is currently listed as "unexplained." An autopsy will be held next week.

Saldanha's family issued a statement. saying, "We are deeply saddened by the loss of our beloved Jacintha. We would ask that the media respect out privacy at this difficult time."

The Australian radio station behind the phony phone call also issued a statement Saturday, stating it did nothing wrong and there was no way to have foreseen the tragic outcome.

The suicide of the London nurse who was "pranked" by two Australian radio DJs has incited outrage from around the globe. So, we gotta ask …

The two Australian DJs behind the Kate Middleton hospital prank that may have led to the suicide of a nurse have decided to REMOVE themselves from the airwaves.

Southern Cross Austereo, the company that owns the station, has released a statement ... saying, "SCA and 2Day FM are deeply saddened by the tragic news of the death of nurse Jacintha Saldanha from King Edward VII’s Hospital."

SCA says the CEO has spoken with both of the DJs ... who are both "deeply shocked" over the tragedy.

The two Australian DJs at the center of the Kate Middleton hospital prank have gone RADIO SILENT since news broke that the nurse at the hospital committed suicide ... TMZ has learned.

The DJs are under serious fire after pulling off a stunt where they pretended to be the Queen of England (fake voice and all) and duped nurse Jacintha Saldanha into connecting them to the people treating Middleton, who revealed details about Kate's condition.

Saldanha's body was discovered early this morning ... and cops believe it's an obvious suicide.

TMZ called the Australian radio station where the DJs work ... and were told by the executive producer that the DJs will NOT be taking any calls, period.

The E.P. explained ... the DJs have been "ordered" not to speak to the media. It's unclear who issued the order.

The producer added, "I advise you to stop trying to call them."

8:30 AM PT -- Law enforcement sources tell us ... cops are NOT planning on conducting a criminal investigation into the death at this point ... and believe there was no foul play.

We're told a post-mortem examination (autopsy) is currently being scheduled and is expected to be conducted in the next few days.

Meanwhile, Kate and William's rep has issued a statement on behalf of the royals saying they are "deeply saddened" by the news ... adding, "Their thoughts and prayers are with Jacintha Saldanha’s family, friends and colleagues at this very sad time."

A nurse at the hospital where Kate Middleton was treated for morning sickness this week has been found dead ... and suicide is suspected -- after she mistakenly transferred a prank radio call to Kate's hospital room.

According to law enforcement, the woman was found dead at an address near King Edward VII hospital, where she worked, around 9:30 AM this morning.

Paramedics were dispatched to the scene but were unable to revive her. Scotland Yard is treating the death as a possible suicide.

The woman -- a nurse identified as Jacintha Saldanha -- was the victim of a prank by an Australian radio station, which called King Edward VII hospital on Wednesday pretending to be the Queen of England (with a terrible accent) and asking to speak to Kate.

The nurse immediately transferred the call to Kate's room, where another nurse then nervously explained Kate's condition over the phone. The call was broadcast all over the planet.

The radio station issued an apology just hours after the prank aired, saying, "We were very surprised that our call was put through. We thought we'd be hung up on as soon as they heard our terrible accents. We’re very sorry if we’ve caused any issues and we’re glad to hear that Kate is doing well."

Prince William and Kate Middleton's unborn heir is already raking in the best baby gear money can buy ... for FREE! And yes, it's totally weird to be jealous of a fetus -- but we are.

Kate Middleton has finally been discharged from the hospital ... after several days of treatment for "acute morning sickness" ... and now the Duchess says she's headed back to her palace to rest.

Kate was all smiles on her way out of the King Edward VII Hospital in Central London ... clutching some flowers ... and getting some assistance from her hubby Prince William.

Afterward, Kate's team of Royal statement writers released the following royal statement, "The Duchess of Cambridge has been discharged from the King Edward VII Hospital and will now head to Kensington Palace for a period of rest."

“Their Royal Highnesses would like to thank the staff at the hospital for the care and treatment the Duchess has received.”

God save the fetus.

Kate Middleton is only a few weeks pregnant ... but already being SHOWERED with lavish gifts from tons of baby product companies ... all gunning for what could be the HOLY GRAIL of preggo publicity.

TMZ has learned ... Kate has already received swanky goodie-baskets from at least 4 U.S.-based baby product companies ... and presumably dozens, if not hundreds, more from around the globe.

The logic is simple ... Kate likes the goods ... uses goods ... is photographed with goods ... goods get WORLDWIDE publicity ... company makes a bloody fortune.

So far, we know Kate been sent kiddy learning programs from MyTalkingToddler.com ... morning sickness relief from a company called One Step Ahead ... and clothes and products from 2 high end L.A. baby boutiques.

We spoke to a rep for Bel Bambini in Beverly Hills ... who told us they sent Kate a $2,300 gift basket which included a new Bugaboo Cameleon 3 stroller (worth $978), a Fendi layette set ($265), Dior Booties ($275) and much much more.

Kate also got more than $1,000 in free baby swag from Flicka -- a high-end baby store owned by "General Hospital" star John Reilly. Management tells us they shipped over their "hot selling Choo Choo blankies" which have been worn by a whole bunch of celeb babies.

Looking like your average suburban father heading to the mall on a Saturday, the 30-year-old Duke of Cambridge rocked a comfortable baggy sweater, worn in easy fit khakis, dark dress socks and a pair of sensible walking shoes as he made his way to King George VII hospital in London today -- where Kate is being treated for severe morning sickness.

Prince William officially put a baby inside Kate Middleton's belly -- which is great news ... unless you're Prince Harry. Sorry royal dude, the queue for the throne just got longer.

Soon-to-be dad Prince William just took a big breather today in London, finally exiting the hospital where his preggo wife Kate Middleton is being treated for severe morning sickness.

William left the King Edward VII hospital moments ago with his royal entourage. The guy's been there since Kate was admitted earlier today.

As we reported, the Royal Palace made the big announcement this morning -- Kate is in the "very early stages" of pregnancy.

Kate Middleton just announced ... she's got a CRUMPET IN THE OVEN!!!

The Royal Palace has released a statement ... confirming Middleton is preggo with Prince William's royal fetus.

The Palace did not say exactly how far along Middleton is ... but noted she was in the "very early stages" of the pregnancy.

According to Middleton's reps, Kate was admitted to King Edward VII Hospital in Central London with severe morning sickness ... and will remain in the hospital for several days.

Kate and William were married back in April 2011. This is their first child together.

If the child is born while Elizabeth II is still alive, it instantly jumps Prince Harry and becomes 3rd in line for the throne.

... which means more time for naked billiards!
