Billboard Music Awards: Meghan Trainor Performs "No"

The show aired live on ABC from the T-Mobile Arena in Las Vegas.

Meghan Trainor walked through the crowd at Sunday's Billboard Music Awards while singing her new hit single "No."

Rocking long red locks and a multicolored sequined dress, the singer changed into her second look of the night after first walking the magenta carpet in a similarly shiny knee-length number.

The performance marks Trainor's second consecutive gig at the BBMAs. At last year's show, she and John Legend sang "Like I'm Gonna Lose You."

Trainor's hit song "All About That Bass" won two BBMAs at the 2015 awards show, including top digital song.

This yera's kudocast is being hosted by Ciara and Ludacris, and includes performances from Rihanna, Madonna and Demi Lovato.
