Bradley Cooper and Zoe Saldana celebrated 2012 by 20-minute-kiss
The Hollywood heartthrob and the sexy actress attended a private 1940s-themed party on New Year`s Eve (31.12.11) at a Bel Air property in Los Angeles
When the clock struck midnight, the lovebirds embraced each other for a lengthy smooch.
A source told UsMagazine.com: "They were making out for 20 minutes!"
Bradley and Zoe met on the set of new movie `The Words` but only started dating after the 33-year-old actress split from her fiance Keith Britton in November.
The source added: "They`re dating, but Zoe just left an engagement. She`s just looking to have fun."
Bradley, 36, was named People magazine`s Sexiest Man Alive last year and he proved the title was justified by romancing a bevy of famous beauties, including Renee Zellweger, Jennifer Lopez and Olivia Wilde.
However, the `A-Team` star tried to play down his sex symbol status in the wake of receiving the honour.
He said: "Oh, it`s just so awful. I`m finally at an age where I really don`t care about anything like that anymore, which is wonderful thing, and then it happened. And then I started to realise just how not sexy I am.
"I have a lot of moments where I`m walking out and I`ll open up the door and think to myself, `I could do that a lot sexier`."
