Prince Harry lived up to his nickname, the Party Prince, Friday night in Belize.

Investigators in England have launched a probe into the murder of a woman whose body was found on Sandringham Estate, which is used by Queen Elizabeth II.

A dog walker discovered the body New Year's Day near the horse-breeding grounds at Anmer, a small village on the 20,000-acre estate which is open to the public. (The Sandringham house itself is a private property exclusive to the royals since 1862.)

“The circumstances suggest this is a murder case and we are looking at missing person’s reports and cold cases both locally and nationwide," Detective Chief Inspector Jes Fry said in a news conference Tuesday from the Sandringham Estate. “The body had been there for some time.

“At this stage we do not know who the victim is,” Fry said, adding an autopsy was scheduled for Tuesday.

Their loyal subjects turned out by the thousands to see Prince William and Kate, along with several other members of the British royal family, walk to and from church Christmas morning.

Kate was dazzling in an aubergine-colored coat and matching hat. She and William were joined by his father Prince Charles and stepmother Camilla, brother Prince Harry, and cousins Beatrice, Eugenie and Zara Phillips..Queen Elizabeth traveled by car.

After a traditional turkey lunch, several members of the family were planning to visit the family patriarch, 90-year-old Prince Philip, who remains in the hospital following emergency heart surgery on Friday.

Royal Deja Vu As Kate Middleton Channels Princess Diana

Katy Perry hosted last night's Saturday Night Live and starred in a riotous skit about the royal family. With the he-can-do-anything Bill Hader as Prince Philip and Fred Armisen reviving his cockney-version of Queen Elizabeth, Katy was there as Pippa Middleton.

The funniest moment was when the Pippa and the Queen compared their respective bums.

"I call my ass the IRA," said the Queen/Armisen. "When I walk into a pub, everybody's face explodes!"

Did guest host Katy Perry out-funny surprise guest star Alec Baldwin on the show?

For all the fuss about her sister Pippa, Kate Middleton’s no slouch herself at stealing the show, and RadarOnline.com has the pics.

The Duchess of Cambridge displayed the elegance, class and beauty befitting of royalty Monday, looking nothing short of amazing in an emerald green dress she wore to a media reception held by Queen Elizabeth at Buckingham Palace.

Kate, 29, wowed the 350 in attendance with her Mulberry full pleated shirt dress, which retails for $2,200. The sexy garment was covered in peace signs, a fitting icon for Kate and her husband Prince William, who have spread their goodwill all over the world in their first year of marriage.

The Duchess of Cambridge was suitably somber and conservative for the Remembrance Day service in England on Sunday, and RadarOnline.com has photos of her fashion flashback to Princess Diana.

Dressed in a black double-breasted Diane Von Furstenberg coat, Kate Middleton was almost a mirror image of the mother-in-law that she never met, who wore a very similar outfit when she attended the same ceremony at the Cenotaph war memorial 27 years ago in 1984.
