Angelina Jolie’s sexy kiss with another man!

Brad Pitt is reportedly not happy about the serious chemistry between Angelina Jolie and Scottish actor James McAvoy, Angie’s co-star in the upcoming thriller Wanted, Life & Style reports.

At the end of October, Universal Studios released a steamy trailer and a series of photos from Wanted, including one of Angelina Jolie, 32, and James, 28, in a passionate kiss. “Brad knows it’s only a movie,� says a friend of the couple. “But seeing them together still stung. She hasn’t done anything that erotic since Mr. and Mrs. Smith.�

And the hottest scenes were added at Angie’s request. “When Angelina accepted the project, she brought in one of her favorite writers, Dean Georgaris, to improve her scenes with James,� says a friend of Angie’s. “The changes meant she spent way more time with James, and the sexual tension got a lot more intense.�

And Angie’s had another new man by her side — a bodyguard named Billy. “Angie used to use Mickey Brett, their main security person, for her routine bodyguard work,� says a friend of Brad and Angie’s. “He’s all business all the time. But recently this new guy — a younger, better-looking one — has been handling day-to-day outings with Angie.�

Billy, says an insider, is in his 40s (like Brad), is Scottish (like James McAvoy) and has worked with the British Secret Intelligence Service. “Brad and Angie trust him with their lives and the lives of their children,� says the insider.

But the couple’s friend says Brad’s noticed Angie and Billy laughing like close friends, which makes Brad uncomfortable. “He worries that Angie could be developing too close of a bond with the new security guy
