Taylor Swift met Prince William at the Winter Whites Gala in Aid of Centrepoint at Kensington Palace in London on Tuesday evening, and even though she's one of the most successful singers in the world, even she was a little bit starstruck!

"Oh my God, this is so incredibly exciting to be performing at Kensington Palace," she gushed to Us Weekly. "With the snow, the lighting, the decorations, it's all so Christmas-y. It's kind of surreal, right? I'm at a palace! I'm just soaking it all in. It's going to be a great night."

When asked whether she was nervous about performing, she joked, "I try not to think about that!" Swift sang "Trouble," "Love Story" and "Fifteen," but not before taking the stage with Wills and Jon Bon Jovi for an impromptu performance of "Living On A Prayer." Check out the video below!





This was her first royal engagement, and after meeting the Duke of Cambridge, she told reporters, "He's so funny! I was really happy he was funny."

Before she performed Taylor told the crowd of 600 people, "I have to thank you, Prince William, for having me. It’s amazing. To call attention to this age group especially, teens and young adults." Centrepoint "is the UK's leading charity for homeless young people, supporting 16-25 years olds with housing, learning, health and life skills," according to their website.

Jennifer Love Hewitt welcomed a daughter with Brian Hallisay on Tuesday, and not only that, but the proud parents secretly tied the knot!

"Jennifer Love Hewitt and her husband Brian Hallisay are thrilled to announce the birth of their daughter," the star's rep said in a statement. "Autumn James Hallisay was born on November 26."

"We're so thrilled and happy to start a family," the couple said in a statement back in June. The two have been dating since 2012, and Us Weekly reports that the duo "got married recently in private." Hewitt and Hallisay appeared together on the NBC series Love Bites, and after teaming up again on the set of The Client List, sparks flew. Yay! So glad J. Love got her happy ending...

Kim Kardashian is a busy bee! The reality star braved the elements in New York City on Tuesday, even pushing baby North West's stroller through the rain. Wearing a Chicago band shirt, white jeans and nude sandals, Kimmy K definitely didn't seem like she was dressed for a downpour. The same day she was out for a rainy stroll in the Big Apple the reality star also tweeted out her praise for Seth Rogen and James Franco's "Bound 2" shot-for-shot parody video, "Bound 3," which went viral yesterday.

Kim wrote to Seth, "You nailed it!!! Sooo funny!" on her Twitter and even retweeted a link with the video. The 32-year-old also wrote that her fiance really dug the video, writing, "Kanye says what's up! He loves u guys! He laughed so hard at this."

So Kim is saying Kanye laughed at their "Bound 3" video? Umm sure he did, Kim. We definitely believe that the man who likens himself to Jesus, "invented" leather jogging pants and flipped out at Jimmy Kimmel CAPS lock-style, watched the vid and had a good ole' knee-slappin' chuckle fest -- ya know, 'cause Yeezy seems to have a really great sense of humor about himself and doesn't take himself seriously at all. Riiiiight!

Seth tweeted back to Kim, saying, "thanks! Some of those positions were really uncomfortable. That sh*t is harder than it looks." Difficult positions or not -- we are so glad the famous buddies decided to stick it to the over-the-top couple's ludicrous music video -- we had quite the laugh in the X17online offices watching it.

While we don't know Kimye's private reaction to being called out for making a ridiculous video (we don't really believe either thought it was funny), at least the self-proclaimed power couple is having a good sense of humor about it publicly!

Harry Styles stopped by Saint Laurent Paris in New York City on Tuesday afternoon, and we're not sure if the One Direction hottie was shopping for himself or lady friend Kendall Jenner, but he spent quite a bit of time perusing the high-priced threads in the store.

The other day Harry went to dinner with Kendall at Craig's, and the next morning we caught the singer leaving Bruce Jenner's Malibu pad. Harry grabbed a bite to eat and then returned to Bruce's home, so even though he's tiptoeing around questions about his relationship with Kendall, it certainly seems like there's something going on.

This isn't the first time Harry has shopped at YSL Saint Laurent Paris -- he paid a visit to the store back in August, so clearly the guy has a love for fashion. Maybe he stocked up on some new skinnies? It seems to be his thing lately...

Does this mean she's finally giving up?!

Khloe Kardashian hit the gym in L.A. today, and the reality star wasn't wearing her massive diamond wedding ring, which makes us think that she's finally pulling the plug on her troubled marriage to Lamar Odom!

Although the Keeping Up with the Kardashians star has been sporting her bauble throughout her trial separation with the Clippers star, his recent incoherent video where he rambles about cheating on her behind her back might have been the last straw!

The brunette bombshell has never looked hotter, and we think she should just dump her husband and find a new man! Her celeb pals like Nicki Minaj and Katy Perry should play matchmaker for her!

Lam Lam really screwed up, because Khlo is a major catch!

Alec Baldwin has been fired by MSNBC, according to Page Six, and though it's not confirmed that it was because of his alleged use of a homophobic slur, his show, Up Late With Alec Baldwin, was yanked from the air immediately after the incident.

"The decision has been made. He's gone," an insider tells Page Six. "The Comcast guys have decided. Word is spreading through the building." The show premiered on October 11 with very low ratings, so even if Alec hadn't angered the public (not to mention every civil rights group out there), it sounds like the program would have been given the ax eventually anyway.

Another source said that Alec's "diva-like behavior toward co-workers" contributed to his dismissal, and the final straw came when he demanded a separate makeup room that was being used by a woman with cancer who was sensitive to hairspray. When Baldwin was told he couldn’t have the room to himself, he allegedly screamed, “I don’t give a f*ck if she has cancer or not, I want that f?*cking makeup room.” What a rude little pig!

Baldwin's rep and MSNBC wouldn't use the f-word (fired, that is), but they did say in a statement, "We are jointly confirming that Up Late will not continue on MSNBC." MSNBC added that this is "mutual parting and we wish Alec all the best."

Such a gentleman, this guy!

On Monday night Mila Kunis and Ashton Kutcher enjoyed a romantic dinner at Carlitos Gardel Restaurant in Los Angeles, and when the lovebirds were ready to head home, Ashton got so annoyed with photographers he actually shoved one lensman and hit the guy's camera ... Rude!

Ashton came out first to try and throw everyone off, and when he was busy chasing photogs away and telling them to "get lost," Mila and a pal attempted to sneak into his black Tesla. We know Ashton isn't a fan of having his photo taken, but you'd think he'd be used to it by now, especially after having a handful of high-profile romances over the years...

TMZ reports that there are "rumors" that Mila is pregnant, and according to a recent report in People magazine, Mila and Ashton are very eager to settle down! "They both want kids. It’s something they’re vocal about," a source told the mag. "I can’t imagine it will be very long before she’s pregnant. [Maybe] right after they get engaged if not sooner. Ashton is definitely planning a proposal. They’re incredibly affectionate. It’s completely effortless."

Looks like Ashley Greene is having a bloody bad afternoon! While filming scenes for her new movie Burying the Ex, the Twilight actress was bloodied, bruised and even got hit by a car! Things are not looking swell for the brunette beauty!

On Monday, our photogs caught the 26-year-old filming her death scene for the film in Los Angeles. But don't worry -- we didn't spoil the end of the movie. In the film, Ashley plays Evelyn, a beautiful but overbearing girl who dies in a freak car accident and then comes back from the dead to haunt her all-around nice guy boyfriend (played by Anton Yelchin) and make his life a living hell.

Sounds like a fun one!
