Romeo Beckham (Burberry)

Romeo Beckham is ready for his close up!

The 10-year-old son of Victoria and David Beckham has been unveiled as the adorable new face of Burberry's spring/summer 2013 ad campaign. Outfitted in a mini trench and clutching one of the company's signature plaid umbrellas, the happy-go-lucky kid strikes an animated pose — like he's ready to go "Singin' in the Rain."

(Denise Truscello/WireImage)Kendall Jenner, 17, and her younger sister, 15-year-old Kylie, didn't let their underage status keep them from enjoying Las Vegas over the weekend. The Kardashian siblings made a Saturday appearance at the Kardashian Khaos store at the Mirage Hotel and Casino, where fans can buy everything from a $35 T-shirt that says "Khloe's My Fave" to a $25 Christmas ornament with a picture of the entire "Keeping Up With the Kardashians" family. The girls donned skinny pants, blazers, and heels — outfits that Kourtney, Kim, and Khloe would certainly give a thumbs up! — as they met with some of their many fans.

So you're a young, single guy in Hollywood who makes the ladies scream, with plenty of money to spend. You want something that says "I have a sexy car," but also "I care about the environment." What kind of ride should you buy? There's just one: the hybrid Fisker Karma, which will set you back at least $105,000 … and that's without the customization that you'll surely want.

Justin Bieber (Christopher Polk/Getty Images)It just wouldn't be the holidays without Justin Bieber rocking out on stage, right? The "Boyfriend" singer, as well as Ke$ha, The Wanted, and some of pop music's other top acts took the stage in Los Angeles on Monday for KIIS FM's Jingle Ball 2012 at Nokia Theatre L.A. Live. For the first time, the radio station planned a two-night event, with Bieber and company headlining the second night. Eighteen-year-old Bieber, with every hair perfectly in place as usual, began his set at about 10:15 p.m., and at one point asked how many ladies in the audience were single, E! reported. Despite that tease, the radio station behind the concert tweeted that Bieber still appeared somewhat taken. "Backstage scoop! @justinbieber is here with @selenagomez and they're looking VERY friendly! @1027KIISFM #JingleBall #awwww," the radio station's official Twitter account read.

(PacificCoastNews.com)"Twilight" is over, but another blockbuster book-turned-movie franchise with a butt-kicking heroine is still very much alive! Jennifer Lawrence, who plays Katniss in "The Hunger Games," spent Monday swimming and shooting a bow and arrow as she and the cast of "Catching Fire," the sequel to "The Hunger Games," filmed in Hawaii. Lawrence, as well as cute co-star Josh Hutcherson, donned wetsuits to take to the water, and she once again armed herself with her signature weapon.

While the 22-year-old actress makes it all look easy on screen, Lawrence has confessed that working out is not something that comes naturally. "I hate [other people] saying, 'I like exercising.' I want to punch people who say that in the face," Lawrence told Glamour in April. "But it's nice being in shape for a movie, because they basically do it all for you. It's like, 'Here's your trainer. This is what you can eat.'"

Kat Von D and Demi Lovato (Twitter)Step away from the tattoo needle, Demi Lovato! The "X Factor" judge tweeted pics of the most recent addition to her impressive collection of ink on Sunday night, along with a photo of herself with the artist, reality star Kat Von D. "Thank you so much @thekatvond for my new ink!!" Lovato wrote of the 12 birds flying up her right forearm. "I think it's beautiful and I love it!!" The new ink sits next to a tattoo of the word "faith" that's also on her forearm (which matches the tattoo of a friend from her days in rehab last year); just below a wrist tattoo of the word "strong"; under a cross on the side of her hand ... and those are only about half of 20-year-old Lovato's permanent tattoos! Yes, people, she has a problem.

Miley Cyrus. (Michael Kovac/Getty Images)"Hannah Montana" is all grown up! It's hard to believe that Miley Cyrus is only turning 20 as she's been acting much older for years. After rising to mega fame as a Disney star, Cyrus took the path that many other child actors have and rebelled against her saccharine-sweet persona. Between sexing up her image, joking that she was a pot head, getting engaged to Liam Hemsworth, and, most recently, chopping off her long beautiful locks, she always keeps us on our toes. In honor of her 20^th birthday on November 23, omg! takes a look back at her five most jaw-dropping moments when she was "just being Miley."
