Phillip Treacy has spoken about Lady Gaga's catwalk appearance during his London Fashion Week show, revealing that the singer came up with the idea herself.

The renowned milliner told the Vogue website: "I went to see Lady Gaga backstage after seeing her at Twickenham [for the Born This Way Ball], and I was telling her about the show and then she just suggested it.

"It was all her idea. She was going to be in Dublin the night before, so she said that she'd fly over for it. Playing to 80,000 people on one night and then appearing in my show the next? Amazing. Of course I agreed."

The popstar opened the proceedings with a speech toasting his first catwalk show in over a decade, wearing a bright pink burka that formerly belonged to the late Isabella Blow.

Treacy explained: "She had this whole concept, she said she was feeling like Isabella. She rang me on her way to the show to apologise for being late - you never see that any more. She really is like a 21st Century pop version of Isabella Blow."

Treacy added of working with Gaga: "She's a really fun person to work with. She has a different sensibility - a different idea of what's perfect and beautiful. She allows me to be really creative and brings my designs to a whole new audience."
