This generation's pop icon, Lady Gaga, stunned at Radio 1's Big Weekend last night (May 15) with her high-octane performance and surprise dedication. 

The singer emerged from a coffin in a black catsuit outfit complete with prosthetic pregnant stomach and opened her set with 'Born This Way'.

Later, she altered the lyrics to Nat King Cole's 'Orange Coloured Sky' and explained to the audience that she wanted to sing it for "Kate and Will" and added, ""I was wishing I was at the royal wedding."

Backstage, after the show, Gaga tweeted:

"Radio 1 show was killer! The Born This Way Itunes Countdown will release my song HAIR 2moro 1pm PST."
