Never one to miss a party, Holly Madison attended the 70th anniversary of “The Wizard of Oz” at Planet Hollywood Resort and Casino in Las Vegas last night (June 2).

Appropriately dressed for the get-together, the Playboy playmate looked cute as she wore pigtails tied with red ribbons, a black and silver dress, and a pair of her own version of the ruby slippers.

Even though she is quite used to showing “her goods” to the world, Ms Madison got a little red in the face this past weekend when her top popped open at a party at PURE Nightclub.

An insider that saw the malfunction go down told FOX Pop Tarts that Holly “was embarrassed but was humbly laughing about the whole thing.”
