Royal Family

Prince William arrived at Reagan National Airport Monday morning as part of his three-day jaunt in the States ... and he rolled with a HUGE entourage of Brits.

Our photog tried to ask William a question -- and he did flash a smile and wave -- but getting any closer would probably have been met with resistance from the gaggle of suited security guards by his royal side.

In an effort to prove he's just a regular, normal insanely wealthy guy ... Prince Harry hit up a youth rugby tournament in England this week -- and taught the sport to a bunch of starstruck boys and girls.

The 30-year-old -- who's also the Patron of England Rugby’s All Schools Programme -- played in a couple of games ... did a little coaching ... and hung out with some rugby pros who were also in attendance.

In unrelated news ... seems Prince Harry is on the prowl again.

The guy reportedly broke up with his girlfriend Cressida Bonas and was recently seen making out with a mystery blonde.

Kate Middleton is knocked up again, and just like last time ... The Duchess of Cambridge is puking her guts out like a sorority chick during rush week.

Power puking -- it's the new Royal thing to do ... when you're pregnant! (Don't get any ideas, Harry)

Get ready for Royal Baby Fever all over again ... Prince William and Kate Middleton are expecting their second child.

Buckingham Palace Kate is once again suffering from hyperemesis gravidarum, as she was when she was pregnant with her Prince George, who was born last July. The condition is like morning sickness, only more severe.

The child will become fourth in line to the British throne ... behind Prince Charles, Prince William and Prince George ... and Prince Harry drops to fifth.

Some guys just can't catch a break.

It ain't exactly Selena Gomez and Cara Delevinge -- but Camilla Parker Bowles and her girlfriends are getting their party on Ibiza-style too.

The Duchess of Cornwall flaunted her crown jewels on a boat, while wearing a red one-piece -- that looks exactly like the classic "Baywatch" suits. Suck it Pam Anderson.

No sign of Prince Charles ... seems like Camilla's on a girls-only trip. Look what you're missing, Chuck.

Here's something to get Queen Elizabeth's britches in a bunch -- video of one of her famous Royal Foot Guards slacking on the job, but in a pretty funny way.

The radical break with royal tradition went down at Buckingham Palace ... where the guard in question decided to put on a show for tourists -- cracking smiles, making faces, and sticking out his tongue.

QE2's protectors usually stand stoned face and never react to anything.

It consists of a thousand blades ... was forged together with the hot breath of an ancient dragon ... but Queen Elizabeth II didn't seem to impressed today when she laid her eyes upon the Iron Throne.

QE was out in Northern Ireland checking out the set of "Game of Thrones" when she got up close and personal with the chair reserved for the ruler of the Seven Kingdoms.

During her tour of the set, Lizzy met a bunch of the cast members ... including Lena Headey, Maisie Williams, Sophie Turner, Kit Harington, Rose Leslie and Conleth Hill.

As for the Queen's REAL throne -- it's pretty pimptastic.

Did someone order a redheaded Prince?

Newly single and ready to mingle, Prince Harry hit up the pool at the Soho House in Miami Thursday while in town for a friend's bachelor party. Harry reportedly just broke up with Cressida Bonas after nearly two years together.

Harry and his friends partied at LIV nightclub at the Fontainebleau Hotel Wednesday night ... after dinner at Hakkasan. We're told Harry was rolling with about 13 guys at the club (not including security) and partied till about 2:30 AM.

HOW DELIGHTFUL!

Looking like the uncoolest person on the planet, Prince William did his best poor person impression Wednesday, hitting the "decks" for some "spinning" in Australia ... and Kate Middleton was obviously his only biggest fan.

Big Will and Kate are currently on a tour of New Zealand and Australia, and today's stop was the Northern Sound System in Adelaide, where William got some DJ lessons.

After dropping some "fat beats," William then pulled a Bieber, hitting up a nearby skate park for some "tagging." Or whatever the kids call it.

Queen Elizabeth II gave a speech during a dinner in Windsor in honor of the President of Ireland, Michael D. Higgins, marking the first state visit by a president of the republic since it gained independence from neighboring Britain.

Kate Middleton and Prince William began their three-week royal tour of New Zealand and Australia today ... and were greeted with a traditional Maori welcome by some of the locals.

Prince Harry, Alexander Skarsgard, and "300" actor Dominic West are getting down to the wire before their epic race to the South Pole later this month -- and TMZ has obtained awesome photos of their training sessions from around the world.

FYI, Harry, Alex, and Dominic (each leading a separate team) are set to depart on their subzero 208-mile journeys to the South Pole in about three weeks -- with an ETA of December 17 -- and they've been training like madmen for the last year.

Polar guide Inge Solheim -- who is training the three men -- tells TMZ, they're all in phenomenal shape, prepping by ice climbing, skiing, and hiking around the world.

For example, the Skarsgard pics show the "True Blood" actor heavy backpack training in the Santa Monica mountains in September -- then camping, cross-country skiing, and cold weather conditioning in Norway in October.

The trek is being planned to raise awareness for a charity called Walking with the Wounded, which raises funds to benefit wounded veterans around the world.

May the best man win, but we still gotta ask ...

Just 3 months after giving birth -- Kate Middleton's flat, ripped, royal mid-riff accidentally popped out in front of a bunch of London photogs.

That's what the Duchess wants you to believe, anyway ... but one conspiracy theorist ain't biting!

Kate Middleton allegedly had a baby 3 months ago -- but there is zero proof of that in these pics of the Duchess of Cambridge flashing her royal midriff all over a volleyball court.

Prince William's wife showed up for a public appearance in London yesterday, sporting wedge heels, and a banging bod that made everyone forget she was ever pregnant.

Kate gave birth on July 22 to Prince George ... and obviously hit the gym on July 23.

Women ... begin hating. Guys ... continue wishing you were Prince William.

It's a stripped down battle of the buns!
