Holly Madison Celebrates "Wizard of Oz" Anniversary

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.
