What had ET readers buzzing this week?

1. Prince William & Kate Middleton Expecting a Baby

After much speculation and anticipation over the past year, the royal palace has confirmed that Prince William and Kate Middleton are expecting their first child.

An official statement issued Monday announcing the news reads: "The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall and Prince Harry and members of both families are delighted with the news."

The statement added that Kate was admitted to a London hospital on Monday to be treated for hyperemesis gravidarum, a more severe form of the nausea and vomiting that normally accompanies the early stages of pregnancy. The Palace said that William traveled with Kate to the hospital in a private car, not by ambulance, and he was spending time at his wife's side.

The statement adds: "Her Royal Highness is expected to stay in hospital for several days and will require a period of rest thereafter."

The couple's first child will be third in line to the British throne.

2. Gisele Bunchen, Tom Brady Welcome Baby

Gisele Bundchen and husband Tom Brady received a special gift this holiday season, a baby daughter!

The Brazilian supermodel, 32, confirmed on her Facebook page that she and the New England Patriots player, 35, welcomed their second child together, Vivian Lake, on Wednesday night.

"We feel so lucky to have been able to experience the miracle of birth once again and are forever grateful for the opportunity to be the parents of another little angel," she said of her newborn daughter.

Included in the post was an adorable photo of Gisele tenderly holding little Vivian's hand in her own. This is the third child for Brady, who has a 2-year-old son, Benjamin, with Gisele, and a 5-year-old son, John, with actress Bridget Moynahan. Ben turns three on Saturday.

3. Demi Moore's Bizarre, Star-Studded Night Out

Demi Moore may have been enjoying herself too much on Wednesday night as some peculiar party pics have surfaced of the 50-year-old actress.

Joined by Lenny Kravitz and George Clooney's gal Stacy Keibler in a VIP section, Moore showed up to the Chanel Beachside Barbecue held at Soho Beach House in Miami, FL wearing a little gray jumper and looking to have a good time.

Photos of her cuddling up to Kravitz, 48, while using her hair to cover up her face (or is she eating her hair?) are making the rounds as well as shots of her dancing recklessly. Though the pics are sure to have many questioning her state of mind at the party, the actress was only seen with the energy drink Red Bull.

5. Angelina Jolie to Quit Acting

Does this mean the end of the Tomb Raider franchise? Angelina Jolie revealed on Monday that she plans to bid adieu to acting.

"I have enjoyed being an actress," Jolie, 37, told Britain's Channel 4 News. "I am so grateful to the job and I have had great experiences and I have even be able to tell stories and be a part of stories that mattered and I have done things for fun, but..."

The mother-of-six gave her reasons for quitting her trade, adding, "I will do some films and I am so fortunate to have the job, it's a really lucky profession to be a part of and I enjoy it. But if it went away tomorrow I would be very happy to be home with the children. I wake up in the morning as a mum and I turn on the news like everybody else and I see what's happening and I want to be part of the world in a positive way."

Jolie is currently an ambassador for the U.N. and has been visiting and working with refugees for years now.
