Baby Watch

Kim Kardashian let her baby bump out for air while vacationing in Greece with the rest of the Kardashian clan.

Prince William and Prince Harry bow down to someone else other than the Queen ... the Dark Knight.

The Royal brothers -- along with pregnant Kate Middleton -- went batty acting like little kids checking out props from "The Dark Knight" trilogy at the opening of the new Warner Bros. Studios Leavesden in London on Friday.

Kim Kardashian is being very transparent about her pregnancy.

While out with her baby daddy Kanye West, the 32-year-old mom-to-be rocked a pair of killer heels and a sheer little black dress that exposed her maternity thong in NYC on Wednesday.

With her growing belly getting all the attention these days, it's nice to see Kim isn't neglecting her first baby ... her booty bump.

Tough times have hit Kim Kardashian and Kanye West ... they may not have a roof over their heads to care for their newborn child. The stark reality is ... they may be homeless.

Here's why the couple is in dire straits ...

- Kim's $5 million Beverly Hills home has been sold, and she needs to be out by Aug. 1.

- Kanye's $3.3 million Hollywood Hills house is about to be sold -- and he's already moved out.

- Contractors have ripped apart the couple's new Bel Air estate ... the one they bought in February for $9 million ... and there's NO WAY it'll be ready in time.

So what is a young, struggling couple to do? They're considering the worst option for any couple ... the in-laws. In this case, they may stay with the Queen of F***ing Everything until renovations are completed at the new digs.

But there's one more option they're seriously considering ... renting a crib for $50k a month.

The recession has been hard on everyone.

If pregnant women were capable of jealousy, one would say Kim Kardashian and Jessica Simpson might be a little covetous of Kate Middleton's physique -- 'cause they're all due around the same time, and well, one of these things is not like the other.

The Duchess of Cambridge visited the Willows Primary School in Manchester, England yesterday ... and you could BARELY tell she was with fetus.

Kate's due to give birth to Prince William's baby in July ... the same time Kim K's due ... and Jessica is also expected to deliver kid #2 sometime around then.

Kanye West is doing everything he can to support Kim Kardashian during her pregnancy -- even though he's in Paris working -- and it's costing six figures to do it ... TMZ has learned.

Kanye has been travelling abroad the past few months -- for events, performances and to record a new album -- but is still hitting up Kim's doctor's appointments.

We're told Kanye has made at least three trips via private jet from Paris to L.A. (costing about $100k total) so that he can be in attendance for Kim on her checkups.

Our sources say Kanye even reaches out to the doctors beforehand to discuss the appointments and to make certain his schedule allows him to be there.

The Pope's only been on the job a month ... and already he's getting touchy-feely.

Former Miss USA Ali Landry -- roughly six months pregnant with a baby boy -- visited the Vatican last week and got physical with Supreme Pontiff Pope Francis ... right in front of her husband!

OK, to be fair ... the Pope's hands-on tactics were a special blessing for Ali's unborn baby, and Vatican sources confirmed that.

Either Kim Kardashian has werewolf blood or her pregnancy has triggered a serious regrowth of body hair ... TMZ has learned.

Kim -- the Armenian poster child for laser body hair removal -- has famously zapped virtually every follicle from the neck down -- but sources close to the reality star tell TMZ, her pregnancy hormones have reawakened the slumbering beast.

We're told Kim has recently been forced to wax -- something she hasn't done in years -- and she's already made appointments to get the new hair growth re-lasered after she gives birth.

FYI, increased hair growth is extremely common during pregnancy ... Drew Barrymore even admitted she grew a small goatee while she was knocked up. It happens.

But in Kim's case ... they might want to break out the lawn mower.

Rihanna came out of a medical building in Bev Hills Tuesday ... and said she's doing a lot better, but it's done nothing to stop the pregnancy talk.

Rihanna has cancelled 4 concert dates on her Diamonds World Tour ... which kicked off on March 8.

Sources connected to the singer told TMZ in early March she was suffering from a throat infection. Thing is ... it's been more than a month now and there are clearly still issues.

Because the info coming from Rihanna's camp has been sketchy ... there have been a slew of tabloid stories speculating that she's pregnant.

Kim Kardashian has once again gone black.

The mom-to-be flashed her smooth pregnant gams at the MTV Movie Awards on Sunday.

Kim Kardashian's first child may be rude, drenched in stinky perfume with hairy armpits ... because her place of birth may be Paris.

Kim was sashaying around gay Purr-ee with baby daddy Kanye West last week and sources close to the couple tell us, she stopped into a hospital specifically to scope out the maternity ward.

We're told Kim is seriously considering popping in Paris for several reasons -- the main one being Paris has strict anti-paparazzi laws ... which is why Halle Berry says she wants to move there.

Another reason ... Kanye has a sick pad in Paris.

And it doesn't hurt that Paris is the fashion capital of the world.

How did Halle Berry's pregnant belly go from baby bump to bustin' out in just a few days? It's simple -- popcorn! Umm ... we'll let the little guy who knows zero about birthing babies explain that one.

Just like a batch of gorgeous Jiffy Pop popcorn, mom-to-be Halle Berry's baby bump is blowin' up.

While barely showing any overt signs during the last few weeks, the beautiful three-plus months preggers 46-year-old heated up the premiere of her latest bomb, "The Call", in Rio on Thursday ... and showed off her suddenly huge Halle belly.

Halle Berry did NOT make any deal with soon-to-be baby daddy Olivier Martinez over who gets custody and who pays for diapers ... so says her lawyer.

Celeb lawyer Steve Kolodny tells TMZ a report in Us Weekly is bogus ... a report claiming Halle and fiance Olivier have hashed out a prenatal agreement in which he agreed to pay her child support if they break up. Kolodny says not only is there no deal, there hasn't been a discussion or even a whisper about one.

TMZ broke the story ... Halle is a little more than 3 months pregnant with her second child -- predestined to be a very good looking boy.

Kim Kardashian gets almost as many headlines as that other Kim -- so, we're thinking Kim Jong Un should just get knocked up by a rapper. Beats launching World War III ... just sayin'.

It's baby bump's first red carpet ... as a glowing, newly pregnant Halle Berry showed off her growing belly -- and sexy legs -- at the premiere of her new movie "The Call" in Buenos Aires on Monday.

As TMZ first reported, the 46-year-old is three months pregnant with her first child with fiance Olivier Martinez and has learned she is having a boy. Halle already has adorable 5-year-old Nahla from her previous relationship with Gabriel Aubry.

Don't cry for her Argentina ... well, unless you go see "The Call."
