Are these the greatest girlgroup moments in the Radio 1 Live Lounge of all time?

The Radio 1 Live Lounge is never more fun that when we've got a girlgroup in and we've had some good ones in our time (*blows own trumpet*).

M.O joined Clara Amfo on Tuesday for a very special performance of their track Not In Love, plus a cover of JP Cooper's September Song, and it was positively magical.

So, to celebrate, here are some more of our all-time favourite girlband Live Lounge performances.

Annie, Frankie and Nadine are our favourite British three-piece girl group and, before smashing it when they visited the Radio 1 Live Lounge this week, they covered JP Cooper's Perfect Strangers more than six months ago - and that song is STILL in the charts. Those girls sure do know how to spot a smash. They also gave us a taste of their own urban sounds with a v.excellent performance of their own hit, Who Do You Think Of?

Before Camila Cabello's departure, Fifth Harmony visited the Radio 1 Live Lounge and gave this rousing rendition of Elle King's Ex's & Oh's, as well as performing their hit single Work From Home.

Oh Little Muffins, taking on Whitney Houston’s I Wanna Dance With Somebody was a bold move… but you ladies totally pulled it off – and mixed with Jason Derulo’s Want To Want Me, too. But, of course, this isn’t the only time Little Mix have completely slayed the Live Lounge. Just check out their version of Mumford & Sons’ I Will Wait…

Oh and don't forget their MEGA mash-up of Jay Z, OneRepublic and Nirvana.

Girls Aloud had many a memorable Live Lounge performance during their reign over the UK charts, but this cover of Labrinth’s Beneath Your Beautiful was one of their loveliest.

What could be better than The Saturdays covering Drake’s Hold On We’re Going Home? The Saturdays mashing up Drake’s Hold On We’re Going Home with TLC’s No Scrubs and Destiny’s Child’s Survivor, that’s what.
