There was an X Factor reunion in London last night (February 15), when Simon Cowell, Louis Walsh and Sharon Osbourne enjoyed an evening out together at The Arts Club, with Cowell's ex-girlfriends Sinitta and Mezhgan Hussainy also present. The former judges were in high spirits as they left the establishment, with Osbourne leaving her red lipstick on Cowell's face as they shared a kiss.

Also in the capital, celebrities arrived for day one of London Fashion Week. Pixie Lott, Laura Whitmore and Kate Nash were among the headliners sat in the front row of the catwalk shows.
