Liberty X and Enrique Iglesias have opened the Harrods July sale for owner Mohammad Al Fayed.
Hundreds of fans gathered outside the Knightsbridge department store as the Popstars band performed.
They played their number one single Just A Little and an earlier hit Thinking It Over.
Liberty X were brought to the store in a horse-drawn carriage.
Latin singer Iglesias arrived in an open-top Rolls-Royce Phantom and was welcomed by Harrods boss Mohamed Al Fayed.
