Model Suki Waterhouse is using her birth name in the hope of becoming a Hollywood star.

The 21-year-old, who is dating The Hangover actor Bradley Cooper, has gone back to calling herself Alice when speaking to movie bosses, after launching a career in acting, because Bradley thinks she will be taken more seriously.

"Suki isn't a name that's going to make a mark in Hollywood - Alice is far better for her, according to Bradley. Bradley is really getting behind her acting career and using all his contacts to get her into the Hollywood fold. But right now he wants he wants her to be known as Alice Waterhouse. He thinks that's a good solid name and more likely to be taken seriously," a source said.

The British star appeared in an episode of BBC One's romantic comedy Material Girl in 2010, and has had roles in films Rachael, Pusher and Love, Rosie.
