Mollie King, Gabby Logan, and Sean Lock were among the stars helping to celebrate the £9million raised by British Airways for Comic Relief on Thursday.
The Saturdays' star wore a monochrome buttoned up shirt with a tan leather skirt. Joining the singer was sports presenter Gabby Logan who wore leather trousers with sharp stylish heels and a grey jumper.
Held at The Brietling store in London, the event was also attended by stars of comedy, including Angus Deaton, John Culshaw and Sean Lock.
John and Sean performed for the guests, and were later joined on stage by Comic Relief Director Emma Freud, who thanked guests and British Airway's Flying Start program for reaching the milestone figure.
