Some are asking "How did Boa get into Ben Lyon’s party?"
Answer: She was invited.
Boa was actually asked to perform at Ben Lyon’s birthday party at Body English in Las Vegas. From the pictures below, the Boa seems to be getting friendly with the DJ…. and the DJ seems to be checking her out (in video). If she wants her music to get air time, this is a smart move….
For those not aware, BoA Kwan is the "Britney Spears of Korea", somewhat notorious in these parts for being one of many "stars" who attended the birthday bash of "film expert" Ben Lyons. I am not sure which is more sad: that Ben Lyons crew asked her to perform, or that she said yes.
