Pumped up with the holiday spirit, Holly Madison celebrated St. Patrick's Day in a revealing green costume. The former Playboy girl rang in the Irish festivity by hanging out at O'Shea, the only Irish-themed casino in Las Vegas Strip, with Brian "Lucky" Thomas who dressed up as leprechaun.
At the noon celebration, Holly was seen holding tall glass and lollipop which are both green. She also challenged people on beer pong games. This will continue in three days to come as a part of the four-day-long block party organized by O'Shea.
Holly wrote on her Twitter about the March 17 celebration, "Channeling my inner Celtic princess for ...beer pong with a leprechaun!" Later she added, "I love wearing costumes all the time. I should be a Harajuku girl.''
