Sugababes Mutya Keisha & Siobhan head to Olympics Opening Ceremony looking amazing together

We still haven't *quite* got over our excitement at the fact the original Sugababes line-up have reformed.

And today Mutya, Keisha and Siobhan proved just HOW perfect they look back together as they headed to the Olympics Opening Ceremony.

The trio, who've announced their new name as Mutya Keisha and Siobhan - or MKS for short - looked as if they'd never been apart as they posed together in London.

Co-ordinating their outfits in tailored cropped trousers and silk colour pop blouses, the girls looked perfect together as they posed for the camera.

The singers, who are reportedly featuring on the track for tonight's ceremony along with Blur, Oasis and Arctic Monkeys, tweeted: "Enroute to Olympics Opening Ceremony".

And Keisha has already got in the spirit of things, by making sure her nails were supporting Team GB.

MKS tweeted: "Keisha being patriotic" alongside this snap of Keisha's Union Jack nails.

And as well as posting this group shot on their joint Twitter account, the girls made sure they each had a go at posing.

Keisha gazes sexily at the camera as she sits with one knee and one elbow up, showing off her LOVE tattoo on her left arm.

And Mutya made us LOL by kicking her leg in the air, while laying back on a sofa in printed leggings and Converse.
