LeAnn Rimes worked her sexy magic at the 5th Annual Hollywood Domino Gala at Sunset Towers Hotel.

The 29-year-old country songstress wore a plunging white Tom Ford dress and gold heels ... also from the designer. LeAnn's Martin Katz jewelry looks stunning!

Proceeds from the event are for “Artists for Peace and Justice” foundation, which "finances and coordinates a wide-ranging education, health and dignity program on behalf of the children of Haiti."
