Matt Damon felt awkward during kissing scene with Angelina Jolie

Matt Damon and Angelina Jolie have been good friends before they acted together in the movie "The Good Shepherd".

They know each other through mutual friend, which was Angelina Jolie's ex husband Brad Pitt.

He revealed to Reveal magazine, “We’re old friends so it was like kissing my sister and really awkward, and generally awful.” 

Angelina, on the other hand, she couldn't care less, saying, “In reality, both the people we’re involved with couldn’t have cared less about that because they know us. You know, it’s one of those things where it’s like the least threatening person. You know, good luck to you guys, I hope it’s not too awkward."
