Oh, young lovebirds Justin Bieber and Selena Gomez, sharing a slice of pizza.

That’s precisely what went down in Las Vegas on Sunday night, as the teens partied after their PDA show at the Billboard Music Awards.

Following the telecast at the MGM Grand, Bieber and Gomez sneaked off to the Cosmopolitan Hotel, according to an onlooker. The two got a tip that the property has a secret pizza joint that serves New York-style slices.

A hostess from Jaleo restaurant confirmed the hidden treat, and the couple ran off; later they were spotted wandering the property munching in their formalwear. The hotel also saw celeb diners Rihanna, Beyonce and Jay-Z sharing a table at Milo’s, a Greek joint, where U2’s Bono was just one table over.

The night before the awards, Billboard magazine hosted a pre-bash at Bank nightclub at the Bellagio to drum up excitement, attended by actress Jamie Chung of ‘The Hangover 2.’

Back in Los Angeles, ‘Harry Potter’ actor Tom Felton has been spotted around town, recently hitting up Rodeo Drive’s Lacoste boutique for some summer shopping before a work trip to New York.

And although Billboard offered music’s brightest stars, L.A. hospital Cedars-Sinai celebrated its annual Sports Spectacular on Sunday, honoring athletes such as Blake Griffin, Lindsey Vonn and Troy Polamalu.

The gala, a fundraiser for genetic research, marked its 26th year, prompting NBA star John Salley to say that when it began, ‘[Arnold] Schwarzenegger hadn’t even met his maid yet.’
