Maroon 5's Adam Levine, fellow singer serenade models

Models Anne V. and Nicole Trunfio got matching 23rd birthday presents when their singer boyfriends, Adam Levine and Ryan Leslie, decided to serenade them at Meatpacking District club SL. "Ryan first started singing his 'Diamond Girl' to Nicole, which led to Adam singing one of his songs to Anne," says a spy. "It was cute." Maroon 5 frontman Levine and Anne V. later ended up at Avenue, where they drank champagne and engaged in "heavy PDA," according to a witness. Also there were Paris Hilton and boyfriend Doug Reinhardt -- "She seemed healthy and was only drinking Coke and Red Bull," our spy says.
