The Salute hitmakers were due to sing on BBC Radio 1 on Monday (07Dec15) as part of the station's Live Lounge sessions, but the appearance was axed as two of the bandmembers lost their voice.

"We are so gutted to do this but we are having to cancel our performance in the BBC Radio 1 Live Lounge today..." stated a message posted on the group's page. "We got up this morning to rehearse & two of us are losing our voices completely! We didn't want to perform when we knew it wouldn't be 100 per cent... We're gonna wait until we're all healthy and come back when we know we can do an amazing job for you guys!!"

The news comes just days after the girls performed at the Capital FM Jingle Bell Ball in London on Saturday (05Dec15).

During the show, Little Mix premiered their latest single, Secret Love Song, a duet with Jason DeRulo, who is now rumoured to be dating bandmember Jade Thirlwall.

Jade's bandmate Jesy Nelson let the news slip, telling Britain's The Sun newspaper, "She's got someone on the go. His name starts with J... then a D."

"He's very hot. It's early days," Jade added.

Jesy went on to compare Jason to Nick Jonas, another performer at the Jingle Bell Ball over the weekend (05-06Dec15), who has been sending Jade private messages via, adding, "Jason's a bit more manly. Nick's a nice boy but Jason, I feel like he'd look after her. She's only little."
