Shania Twain & Meghan Trainor Diss Each Other on 'Drop The Mic' - Watch!

It’s Shania Twain against Meghan Trainor!

The “You’re Still The One” music icon and the “No” pop superstar are trading barbs on the latest episode of TBS’s Drop The Mic.

“When I was told I’d be battling one of my idols, I wondered if beating her was worth the title,” Meghan bragged in a preview of her rap. “Shania Twain? No problem, I thought you meant Dolly Parton.” Oh, burn!

“I don’t need to bow down to come on top. Your lips are moving…I wish they would stop,” Shania sassed right back.

“I’m on @DropTheMicTBS tonight, tune in from 10/9c on TBS. @Meghan_Trainor, bring it on girl!” Shania wrote on Twitter.
