Fuse Favorite: Watch Meghan Trainor on Fuse All Week

Almost out of nowhere, Meghan Trainor's doo-woppy, body-positivity anthem "All About That Bass" (below) has taken the country by storm. The track's been lodged at the No. 1 slot on iTunes for days and just last week soared into the Top 10 of the Billboard Hot 100 in a month's time. See how the 20-year-old stunner is taking in her breakaway success in our in-depth interview above.

"It's like a movie I'm watching, it's not real," the Nantucket native says of her quick rise. "When they tell me, 'No, this is your song. And you're killing it.' I just tear up ... I love Ariana Grande and Iggy, they're killing it. And to be next to them, like, I was next to Jessie JNicki and Ariana on that new song ["Bang Bang" on the iTunes charts]. I was like, 'Mom! What do you mean?!' [Laughs] Girl power! I'm right under them. I was like, 'How?!' It's crazy."
