Meghan Trainor covers 5 Seconds of Summer hit

Meghan Trainor has performed a cover of a 5 Seconds of Summer song.

The US star put her own spin on the pop-punks' track 'Don't Stop' for Fearne Cotton's BBC Radio 1 Live Lounge.

She appeared on the show today (January 20) and impressed by giving the song an almost country feel.

The performance meanwhile came on the same day it was revealed that Trainor has written and recorded a song with One Direction's Harry Styles.

The pair penned the tune 'Someday Maybe', with Trainor calling their session "unbelievable".

She told The Sun: "It's real! It's a duet. It's a beautiful song we wrote together on my ukulele. We even recorded a rough demo together with our vocals together. It's a cute acoustic love thing.

"It's one of the first cool things I got to do with a pop star. A friend of mine said Harry was a fan and said he would love to write with me. He's an incredible writer too. I was worried he'd just be a 20-year-old boy. So I walked in with a prepared verse and chorus. But he gave me very poetic, mature lyrics.

"I was like, 'Well damn Harry, you know what love is'."
