Ryan Phillippe's ex-girlfriend Elsie Hewitt has filed a lawsuit against the "Shooter" actor for allegedly kicking, punching, and throwing her down the stairs.

The suit, first reported by TMZ, alleged that Phillippe often abused drugs and combined them with "excessive alcohol consumption and often exhibited symptoms attendant of poly drug and alcohol abuse, including mood swings and bouts of anger."

Sources close to Phillippe said that Hewitt instigated the altercation.

"Elsie showed up to Ryan's house uninvited and under the influence a few days after he had broken up with her," the source told People. "She physically attacked Ryan, caused a scene and refused to leave his home. As she was removed from the premises, she claims she fell and injured herself."

Hewitt, a model, is asking for no less than $1 million, though her lawyer insists the money would go to a domestic violence charity.
