Kate Moss paid homage to Lady Gaga as she watched her perform from the front row of an intimate gig, kissing the singer's hand.
The Judas star performed four songs at Annabel's private members club in London on Thursday. She changed a line in the song Born This Way to "he made you perfect, Kate" instead of "babe", in tribute to the supermodel.
An insider at the Belvedere Celebrates Born This Way at Annabel's gig said: "Kate was sat in the front row literally jumping up and down in her seat. It was quite the epic moment and she went crazy, kissing Gaga's hand."
Florence Welch, Will.I.Am of the Black Eyed Peas, Stephen Fry and Geri Halliwell were also among the audience watching Lady Gaga perform in a green veil and a leopard-print, skin-tight body suit.
Earlier the Poker Face singer appeared on The Graham Norton Show in a wedding dress.
Lady Gaga told Graham: "I'm not dating. No, there's no boyfriend. No, I'm miserably pathetic in my wedding dress. I haven't been on any dates recently because I have been working so hard and I get very bored very quickly with men."
She added: "I guess they would get freaked out by this wedding dress."
The Graham Norton Show airs on BBC One on Friday at 10.35pm with Gwyneth Paltrow, Geoffrey Rush, and comedian Jason Byrne also as guests.
