Brad refused to kiss co-star?

"On January 22, Brad refused an on screen kiss with sexy co-star, Megan Brown, on the set of his new drama The Curious Case of Benjamin Button. A source tells Star, “The feeling among the crew was that Angelina didn’t like the girl because she was stunning.” Angelina’s afraid he’ll fall for Megan, just like he did for her while filming Mr. & Mrs. Smith in 2005.’ Meanwhile, an official at Pictures Paramount said he has “no knowledge of this particular scene.”

I don't believe it. Plus they ended up doing the scene.
