Bradley Cooper has reportedly advised his girlfriend, model Sukie Waterhouse, to use her birth name, Alice, when pursuing acting roles.

The 21-year-old model has been dating the Silver Linings Playbook star since February and a source told The Sun that he is using his contacts to help her to launch an acting career.

"Sukie 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 her to be known as Alice Waterhouse."

The source added, "He thinks that's a good solid name and more likely to be taken seriously."
