Lady Gaga arrived onstage in a gold coffin wearing a prosthetic pregnant stomach last night.
The 'Hair' hitmaker emerged onstage in Carlisle, Northern England, from the velvet lined box, opening her hour-long set at the Radio 1 Big Weekend Festival with her recent single 'Born This Way'.
The singer performed tracks from her new album - also called 'Born This Way' - as well as older favourites including 'Poker Face' and 'Bad Romance' during the show, which saw her make numerous costume changes, but clad in black throughout.
During her song 'Judas', Gaga wore an eye mask and a crucifix attached to her pants. She also played jazz standard 'Orange Colored Sky', changing the words in tribute to British royal couple The Prince and Princess of Cambridge, who married at the end of last month.
She told the crowd: "When I was in the United States I wished I was at the Royal Wedding. I want to be the girlfriend of a handsome prince."
Gaga also gave a tearful rendition of her track 'Edge of Glory' after explaining to the crowd it was written about her grandfather.
Before her performance - which saw her take to the stage 40 minutes late - Gaga said she wanted it to be a little more "off the cuff" than her recently concluded The Monster Ball Tour shows.
She told BBC Radio 1 DJ Scott Mills: "I'm going to change it up a bit and maybe do a jazz tune. I'm going to see how I feel. It's not the Monster Ball. I usually get a little more off the cuff when I do festival shows.
"I get really inspired by the audience depending on how I feel about the show. It's not completely planned out."
Other acts to appear at the free two-day event, attended by some 40,000 people, included Foo Fighters, Tinie Tempah, Nicole Scherzinger, Jessie J, My Chemical Romance and Bruno Mars.
