Fifth Harmony have teased fans with a snippet of their new song 'That's My Girl'.

The track, which features Tinashe, was previewed in a new advert for the 2016 Rio Olympics.

It features lyrics such as: "Who’s been working so damn hard?/ You got that head on overload."

The tune is due to open Fifth Harmony's upcoming second album '7/27'.

The record will land on May 27.

It had originally been scheduled for release on Friday (May 20), but it was pushed back a week.
