Keyshia Cole didn't have kind things to say about Destiny's Child member Michelle Williams' performance with Beyonce at the Super Bowl. But it's not phasing Kelly Rowland, that's for sure.

"I think I was frightened to blink for a sec.," Cole wrote on Twitter during the performance. "Then Michell sung and woke my ass up from my daze! She always fuckN the groove up."

In an interview with Rolling Stone, Rowland admits it wasn't even something she was aware of. Well, until Cole received the backlash she did.

"It didn't even make it on my radar until other people brought it up," Rowland says. "It didn't even matter. We had a wonderful performance, and that's all I cared about. I was with my sisters and the three of us matter to each other, and that's all that counts. We matter to a lot more people, with all due respect, than her. So, I really don't care what she said."
