You might not know it to look at the smiling pop star, seen here leaving the Patricia Field store in SoHo, but underneath that million dollar smile dwells the brain of a gamer. Beyonce Knowles has confessed to Entertainment Weekly that she loves Guitar Hero and recently filmed an ad for the Nintendo DSi game Rhythm Heaven.

When asked if she would consider creating her personalized version of Rock Band or Guitar Hero, the Destiny’s Child frontwoman answered, “I’ve actually played some karaoke games with the old Destiny’s Child songs. It’s so funny, because I don’t get great scores. I’m like, “How is that possible?!”

She’s lucky those games weren’t around 10 years ago. Her ass might have been tossed out of the band.
