Holly Madison is bikini ready!
The new mom slipped into a revealing two-piece this weekend at the opening of TAO Beach in Las Vegas -- where she showed off her summer bod just six weeks after giving birth to daughter Rainbow.
Madison has reportedly dropped 30 pounds since giving birth and tells Life&Style she did it by doing intense cardio and keeping to a strict diet.
She tells the mag she put on 40 pounds during her pregnancy and aims to get down to 110 pounds -- but adds she's "really proud of how I look right now."
She looks great!
