And now it's time for round two. Singers K. Michelle and Tamar Braxton are hurling insults at each other again.

In August 2013, Braxton accused Michelle of copying her hairstyle and look and threw some shade directed at her on Twitter. On Sunday (May 4), the two jumped back on social media to continue their fight, but this time the beef had to do with lip-synching, as the 'Love & Hip Hop' alumn accused Toni Braxton's little sister of not really singing onstage.

"All and all....I'm saying I'm singing live no matter what anyone says," wrote Braxton. But things didn't stop there, they only got more contentious.

"I mind my own business and they really like to test me," tweeted Michelle. "But I'm a bully. I make music not war." Apparently, the 'Still No F---s Given' creator was accused of starting the whole twitter feud in the first place.

During the first round of their argument, Michelle called Braxton a Kermit the Frog look-alike, and she used the same insult this time around in an Instagram photo.

"Lord, please keep me in your loving arms," she wrote along with the image of the Muppets character. "I've been good. I've shown support. Haven't bothered anybody. I even went to watch the new movie 'Muppets Most Wanted' and Miss Piggy continues to mess with me. I just wanna sing. No more jumping gates. I even do yoga now. I'm trying."
