Meghan Trainor has been added to the line-up for this year's Billboard Music Awards.

The singer will take to the stage at Las Vegas' TMobile Arena on May 22.

She joins a bill that already features the likes of Rihanna, Justin Bieber, Madonna and Ariana Grande.

The event will be hosted by Ludacris and Ciara.

Trainor meanwhile has laughed off an embarssing tumble she took while performing on the Tonight Show on Thursday (May 12).

She appeared on Jimmy Fallon's programme to run through her new single 'Me Too'.

However, at the end of the tune the US star wobbled on her high heels before falling flat to the floor.
