The original Sugababes, Keisha Buchanon, Mutya Buena and Siobhan Donaghy, have performed their first live show since reforming, watch a video of their performance below.

The trio performed on New Year's Eve for an East London party held by Ponystep magazine, and is the three-piece's first live show since their reunion in 2012. The girl group, who have been working with Emeli Sande, among others, on their new record, performed hits including 'Overload' and 'New Year' at the show, which both appeared on the first Sugababes album - the only the trio recorded with their original line-up. They also performed 'Freak Like Me' (which Donaghy did not originally sing on) and a cover of Rihanna's 'Diamonds'.

Donaghy told Twitter followers that the performance marked her best ever New Year's Eve, writing: "Happy new year everyone!!!! Well this certainly goes down as the best yet."

Buchanon, the last to leave the group, said: "Argggh love my sisters," while Buena said that she hoped fans enjoyed the performance. "We promised every1 something frm us by new yrs and we gave it hope u all enjoyed last nite who ever was there an enjoyin it on youtube xxxxx," she tweeted.

The trio no longer hold the rights to the name Sugababes, which is now used by a totally different line-up of female singers.

Siobhan Donaghy quit the group in 2001, Buena in 2005 and Buchanon was replaced in 2009. They are expected to release new material in 2013, and previously revealed they had been influenced by Rihanna on their upcoming new album.
