Duchess of Cambridge Kate Middleton has been discharged from London's King Edward VII Hospital after being treated for Hyperemesis Gravidarium, a form of extreme morning sickness.

Escorted by her hubby Prince William, bouquet of yellow roses in hand, the Duchess smiled for photographers as she made her way home, telling reporters she was feeling "much better."

Middleton, 30, was hospitalized for three days and received frequent visits from her family while on bed rest.

The palace released the following 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."

Jessica Simpson may have a $4 million deal with Weight Watchers, but apparently the news that she got knocked up didn't sit too well with the company!

According to Us Weekly, WW execs are "livid that their new spokeswoman got pregnant just seven months after welcoming daughter Maxwell."

A source tells the mag, "They're furious at Jessica. She was already on thin ice with them since she didn't lose enough for a the first ad, when they had to shoot from the waist up."

As a result, Simpson's second campaign, in which she is celebrating a 70-pound loss, may not even air. "They don't think it can run," the source explains. "No one wants to hear about a pregnant woman dieting."

Uh oh! What next?

Trust us, that's probably a good thing!

Taylor Swift was snapped leaving Cookshop in New York City with several girlfriends on Tuesday afternoon, and later we spotted her heading to the studio. But not to worry -- One Direction hottie Harry Styles paid her a visit around 11PM, arriving at the Greenwich Hotel with what appeared to be an overnight bag.

And this is the second night in a row the two have shacked up! Harry and Taylor returned to her hotel at 4AM on Tuesday after a late night of partying with his bandmates, and several hours later he was snapped doing the walk of shame. Wonder how much sleep these lovebirds are getting?

And thanks to his daughter Seraphina, we got our daily dose of cuteness!

On Wednesday morning Ben Affleck took his middle child to Brentwood Country Mart for an early morning coffee run, and while the Argo actor/director looked a little sleepy, Sera was practically dancing around him in circles!

Ben was recently honored as Entertainment Weekly's Entertainer of the Year, and he also made Barbara Walters Ten Most Fascinating People of 2012 list, so with all this buzz about his latest film project, we have to wonder if his name will be called out on January 15 when Oscar nominations are announced!

Looks like someone's got a lot of gift wrapping to do! Or maybe she'll put her assistant to work?

On Tuesday Hilary Duff went shopping at Paper Source in Studio City, and she emerged with two bags packed full of wrapping paper. This will be Duff and hubby Mike Comrie's first Christmas with their son Luca, who was born last March. The other day Hil tweeted a photo of ornaments and big red bows on their doors and wrote, "It's beginning to look a lot like Christmas." Can't wait to see more holiday pics - you know she's a Twitterholic!

Gwyneth Paltrow covers the new issue of InStyle U.K. and while the mag borrows some quotes from her interview with the U.S. edition earlier this year, there's a few new tidbits, specifically about her desire to have more children!

The 40-year-old actress says she thinks about giving son Moses and daughter Apple a younger sibling, telling the mag, "My brain says, 'Oh, I think I’m done, the kids are big now and I don’t want to go back to changing diapers.' But a part of me would love to have another. Of course, I’m old now!"

Gwyneth, who was interviewed by pal Diane von Furstenberg for the mag, added, "I look for an interesting supporting part about once a year. That’s the most I can manage. Some women can do it and that’s fantastic, but I can’t. You make choices as a wife and mother, don’t you? You can’t have it all. I don’t care what it looks like."

So what does Mrs. Goop say is the hardest thing about her marriage to Coldplay frontman Chris Martin? "Probably our artistic temperaments together. Artists are sensitive; there are ups and downs, mood-wise. Musicians need a certain gravitas and focus in order to write. The temperament that goes with someone who is creative can be challenging."

John Travolta and Olivia Newton-John have teamed up for the holiday track "I Think You Might Like It."

The Grease co-stars seem to still enjoy each other's company after all these years, and John's kids and wife Kelly Preston are also featured in the video.

The song is part of the twosome's holiday album This Christmas. Time to light up the yuletide log and get into the spirit of the season!
