Rebecca Ginos: Adam Levine's All Mine!

Maroon 5 frontman Adam Levine and his girlfriend Rebecca Ginos (cocktail waitress from L.A. nightclub Teddy’s) drop some major dough on some holiday shopping in Beverly Hills on Saturday.

Adam, 28, and Rebecca, 21, spent the afternoon picking up designer duds at Yves Saint Laurent and Prada and were seen waiting for the valet to bring his Mercedes out front.

Earlier this year, Adam shared on the Howard Stern Show he met Rebecca on her 21st birthday. “We had sex the first night we met,” he gladly admitted. “[She's] the hottest girl in the entire f-ing universe.”
