According to In Touch Weekly, Angelina Jolie has purchased a $12,000 motorcycle for her babydaddy's 45th birthday on December 18th. Last year, Angie spent nearly $100,000 on a bike for Brad, but sources tell the mag that this is what Brad really wants, even though its oh, roughly $80k cheaper than his last b-day present.

A source tells the mag, "Since Angie is always in a dilemma of what to buy Brad, she's getting him the new Ducati Monster 1100S titanium. It's a surprise. She ordered it from Italy months ago. It's new and I believe it's not out yet in Ducati stores. I guess a guy can never have too many bikes!"
