Bradley Cooper's alleged plans to have girlfriend Suki Waterhouse move in with him could possibly work in his favor if he really is how his ex-wife now claims in a new book.

 Bradley Cooper, Suki Waterhouse Engaged?

Jennifer Esposito, who was married to the charming American Hustle actor from December 2006 to May 2007, has revealed secrets about the actor in her new book, Jennifer's Way.

The 41-year-old actress spoke about a mystery ex in the book, slamming a man who had a "marching band of red flags" surrounding him, and mentioned several different ways she now admits made him unattractive.

She claimed she didn't find him that attractive, and called him "funny, smart, arrogant and a master manipulator" who had a "mean, cold side" and whose personality could "flip on a dime."

She then wrote about how the relationship came to an end shortly before she landed a role on the sitcom Samantha Who?, which aired in 2007. The Daily Mail reports that the timeline for the mystery ex then seems like it was her one with Cooper.

Cooper has rarely commented on his marriage, and hasn't responded to Esposito's claims.

If he is as manipulative in relationships as his ex seems to claim, it could spell bad news for his relationship with 22-year-old model Waterhouse. The model's career has been taking off in London, but her actor beau wants her to move in with him in Los Angeles, where he is based.

"They've been dating for a year now and things are getting more serious between them. It's just a case of whether or not they're both ready to take it to the next level," sources said.

"Suki's career is flying in London. She's one of the hottest people on the London fashion scene and doesn't want to lose momentum," the source added. "But Bradley is keen for them to live closer together, and has his home and production company, 22, in LA. He's trying to tempt her to move so they won't have to fly around the world to see each other."
