Lady Gaga kept the audience waiting for 15 minutes at Radio 1's Big Weekend in Carlisle.

The 25-year-old New Yorker began her performance by arriving on stage in a coffin wearing a black PVC prosthetic pregnant stomach.

Radio 1 presenters Fearne Cotton, Reggie Yates and Greg James had to unexpectedly fill until the star arrived on stage.
