BBC Radio 1's Twitter called Trainor's version of Don't Stop "a ukulele cover" since she played a ukulele while singing.

Her cover was also praised as being "fab" by the British radio station.

It's a tradition for BBC Radio 1 to invite the biggest acts around to perform their own current hits along with doing intriguing covers. Trainor did just that with Don't Stop.

Prior to diving into the cover Trainor shared, "I love this song. It's one of my favorites from them. And the boys are very sweet and I met them on the Jingle Ball Tour kind of. I met one of them and I thought this song sounded perfect on ukulele."

She was right. 5 Seconds of Summer's Ashton Irwin praised her cover!

"This is hella groovy!!!" he gushed on Twitter, adding, "you rule," to Trainor.
