Meghan Trainor is ‘All About That Bass,’ but at the American Music Awards on Sunday she was all about Kim Kardashian’s butt. The singer walked the red carpet at the AMA’s, and was asked about the Keeping Up With the Kardashians star’s recent debut of her slick-up nude butt on the cover of Paper magazine.

“She has an amazing butt!” Trainor said to E! host Guiliana Rancic. “If I had a booty like that, I don’t know if I’d post it. But she looked bomb.”

Kim Kardashian and Paper set out to #BreaktheInternet with her shiny derriere, but fell short on their goal. Meghan Trainor didn’t fall short on hers, however. She was thrilled to receive her very first American Music Awards nomination for New Artist of the Year, and even though she didn’t win, saw the nomination as a huge boost to her career.

Meghan looked classy in her black peekaboo lace dress by Ted Baker that aptly highlighted her hourglass shape. Bow-topped heels and a bedazzled clutch in the shape of a red smooch completed were the perfect finishing pieces to her ensemble.

PerezHilton.com , on the other hand, reports that Meghan Trainor’s AMA’s look was boring. Perez felt she lacked glamour.

“Sure, she grabbed a crystal-covered lip clutch for a little wow factor, but it didn’t mesh with the rest of her ensem,” he wrote.

Meghan Trainor broke out on the music scene in a big way with her body-loving hit, “All About That Bass.” Her latest release, “Lips Are Movin’,” is destined for the top of the pop charts as well. What did you think of her look on the red carpet at the American Music Awards? And since when did any little black dress lack glamour?
