Keyshia Cole was less than impressed with the Destiny's Child reunion during Super Bowl XLVII. The outspoken R&B singer, 31, shared her candid -- and cruel -- commentary with her 217,577 Twitter followers in a series of posts Feb. 4.

Beyonce Knowles, 31, Kelly Rowland, 31, and Michelle Williams, 32, performed "Bootylicious," "Independent Women Part 1" and "Single Ladies (Put a Ring on It)" during the Mercedes-Benz halftime show; celebrities including Kelly Clarkson, Jimmy Fallon, Sophia Bush and Chris Colfer praised the medley via Twitter.

"F-ck that shit up then Beyonce! Bad bitch central," Cole wrote of the headliner, who also performed a selection of her solo hits. "I think I was frightened to blink for a sec. Then Michelle sung and woke my ass up from my daze! She always f-cking the groove up."

After Destiny's Child fans targeted Cole's Twitter account in defense of the popular girl group, the "Love" singer offered a half-hearted apology. "But hey! I love y'all too!" she tweeted. "And y'all girl is whack and always will be!"

Despite Cole's harsh criticism, Williams was pleased with her performance. "Had a great time with my sisters tonight! Tried to keep it a surprise!" tweeted the singer, who replaced original Destiny's Child members LeToya Luckett and LaTavia Roberson when she joined the group in 2000. "Love you all. God bless!"
