Pictures of Cameron Diaz and Alex Rodriguez in NYC Celebrating Her 38th Birthday

Cameron Diaz was in a tight and short LBD last night to celebrate her 38th birthday in NYC at The Lion with her boyfriend, Alex Rodriguez. Their special evening out was their latest adventure in a Summer full of fun together — they've been spotted taking in a Broadway show, mingling with their A-list pals, and bonding with his kids. Cameron's taking it easy after her big promotional tour for Knight and Day ended, seeming happy to let A Rod have the spotlight as he tours the country playing with the Yankees.
