A rep for One Direction has denied suggestion that Harry Styles hung out with Taylor Swift last night (February 11) in London.

The two pop superstars dated at the end of 2012 before splitting and there has been little in terms of public reconciliation since.

However, rumourmongers speculated that Styles was backstage with Swift at her O2 Arena gig after seeing a video posted by the '22' lady of her 'haircut party'.

The US star was getting her hair cut and numerous people were watching - with people believing some of the figures to be Styles and his friend Cara Delevingne.

However, a rep for the One Direction man has denied that the singer was at the concert.

Swift was performing at the O2 Arena for the last time on her Red Tour run in the UK.
