The Vanity Fair Oscars party was the place to be after the Academy Awards on Sunday night, and many of the A-list guests hopped into the photo booth to commemorate the evening. Katie Holmes posed on the red carpet in a strapless Elie Saab gown alongside husband Tom Cruise, then the two headed inside to chat with David and Victoria Beckham, as well as Lily Collins, before snapping a few photos. Sofia Vergara and her man, Nick Loeb, showed love in the booth, as did Seth Rogen with wife Lauren Miller. There was some affection between pals, too, as a Chanel-clad Emma Stone monkeyed around with Kristen Wiig. Make sure to check out all the Vanity Fair Oscars photo booth pictures!

Kristen Stewart stepped out of her Paris hotel today and stopped to pose for a photo with fans. She joked with photographers, then was on her way. Kristen traveled to France in order to check out Fall Fashion Week. Along with Salma Hayek and Charlotte Gainsbourg, Kristen Stewart went to Balenciaga to see designer Nicolas Ghesquière's Autumn designs. Kristen caused a stir when she took her place in the front row decked out in a pair of hot leather pants. Her boyfriend, Robert Pattinson, wasn't lucky enough to see her in the ensemble. Robert Pattinson's in NYC, where he was seen shopping on the Lower East Side last night.

Zac Efron and Danny DeVito joined a group of children today at the New York Public Library for a reading of Dr. Seuss's The Lorax. Zac and Danny, who both voice characters in the 3D film based on Seuss's fable that opens today, took the stage and read aloud as part of the National Education Association's Read Across America event.

It's been a busy week for Zac. He stopped by Today and chatted with Matt Lauer just yesterday. Zac addressed his red-carpet condom incident and simply explained his new "pocket checking policy" before major events. While Zac and Danny take the East Coast by storm, their other costar Taylor Swift is around the globe in Australia following a romantic weekend in LA. Taylor went on a date with Tim Tebow, according to reports, though it's Zac who plays her love interest on screen.

Ian Somerhalder is featured in April's Glamour, putting his male modeling skills to use for the glossy's "Hot Night In" spread. The latest installment of the magazine features The Hunger Games star Jennifer Lawrence on the cover, but inside, Ian makes the most of his own moment in the spotlight. The Vampire Diaries actor cozies up with a model in bed, makes out with a mannequin, and reveals a sillier side in the pages of the publication. In the accompanying interview, he talks about why he believes in being a nice guy versus a macho man, his Ian Somerhalder Foundation — which supports green efforts — and the most romantic and spontaneous date he's ever devised. He didn't mention his costar and real-life girlfriend, Nina Dobrev, by name when sharing the latter story, but it sounds like she may have been the lucky lady who joined him for the impressive outing. Here are highlights from Ian's interview:

• On once taking a date for lunch in Paris: "Flying across the ocean for one meal was pretty awesome . . . It paid off!"
• On his approach to women: "If you are respectful and nice and charming to a woman, it's a better approach. And I don't know what women want. No one knows what women want!"
• On his passion for the environment: "Kids are meeting in coffee shops and basements figuring out what's unsustainable in their communities. That's the future."
