Yahoo! Finance reports that 24-year-old Fox, who stars opposite Lost actor Dominic Monaghan as one half of a physically abusive couple, has given her salary to the Sojourn House, which provides battered women and their kids with a place to rebuild their self-esteem and their lives. In the powerful video, which also features Rihanna, Fox and Monaghan, 33, are shown alternately attacking each other and passionately making out.

Both Eminem, 37, and Rihanna, 22, have had personal experiences with domestic violence, and as Rihanna told Access Hollywood, "The lyrics were so deep, so beautiful and intense. It's something that I understood, something I connected with."

For his part, Eminem felt it was an issue that needed to be addressed. "Trying to make this tough subject work visually is a challenge," he admitted. "It was great to have Rihanna, Megan and Dominic on board for this. They really brought it and made this video super-powerful."
