What's the best way to grab a crowd's attention? If you're not up on a stage, you need to elevate yourself above the hoi polloi in another fashion. Kelly Rowland chose to show off her tits. Good tactic, Kelly Rowland!
But she didn't want people mesmerized by her breasts, so she put a little tape over the nipples. We're a tad disappointed, but it makes sense; it's about the music, not the body (for some people at least, not us).
