BoA was in attendance at Ben Lyons Birthday party over the weekend at Body English in Las Vegas. Not only was BoA's song "Eat You Up" playing at the party but she actually got on up stage with Ben for a performance. Ben Lyons is a panelist on Daily 10 on E! Entertainment. He is the son of New York film critic Jeffrey Lyons. Ben recently replaced Roger Ebert and Richard Roeper on the long-syndicated critic show "At the Movies." It was interesting to see that Korean American Aaron Yoo was at the party. Aaron was in Korea last month to attend the Pusan International Film Festival, maybe he met BoA and somehow got her a hookup. Anyways it's pretty cool to see an American audience chilling out to BoA's music, at the end of the day it's just music. Albeit a very small sample size, maybe she has a chance to make it over here afterall. Video courtesy of benlyonstv:
