Back Together: MyDaily's Guide To The Sugababes

The Sugababes are back! Well, ish. Remember Mutya Buena, Siobhan Donaghy and Keisha Buchanan - the original members of the girl trio? They've reformed and are releasing a new single called Boys, which is pretty punchy actually.

But here's where things getting tricky. Although they may look and sound like the Sugababes, they're not the Sugababes. Officially, the Sugababes are Heidi Range, Amelle Berrabah and Jade Ewen.

So the three original members - who co-wrote the pop genius that was Overload - are now performing under the name of Mutya Keisha Siobhan or MKS. Got it? Well done.

The original Sugababes were like the really cool girls at school who - although completely terrifying - you knew would totally have your back if you were in their gang. And we wanted to be in their gang. Like, REALLY. Er, still do actually. Girls?
