Listen to Meghan Trainor on iHeartRadio

Meghan Trainor

Meghan Trainor's "All About That Bass" is topping the charts right now. The world is all about that bass thanks to Meghan. 

So is it true that Meghan's mama told her "Boys like a little more booty to hold at night?" Meghan was asked that backstage during an interview with Bobby Bones and Amy before she took the stage at our iHeartRadio Music Festival Saturday night ... and she said it's not true! But she did tell Meghan to "love yourself, and don't worry about your size, you look great."

Meghan also talked about her next single, "Title." Check out a clip from her interview below:
