Lady Gaga believes her upcoming slot at the MTV VMAs will be her most physical performance yet.

The singer is due to sing at the glitzy ceremony in Brooklyn on Sunday (August 25) as the music industry celebrates video-making.

Whilst the US star's performance is something of a secret, she told Capital FM that it is probably her most physically demanding show yet. Gaga said:

"I would say actually that you should try not to expect anything because whatever you're expecting is not going to take place! That's sort of the idea to always create the unexpected. I will just say that it's the most physically challenging performance I've ever done. This is my way of fighting back. I don't like to fight with my words I like to fight with my talents so that's really what this performance is all about."

The 'Applause' lady added: "I'm in New York, we're in the middle of rehearsals, we've been rehearsing for weeks, and we're still going. The performance I did years ago for 'Paparazzi' was kind of a major moment for me as a breakout performer, it was the moment where people really got to see what I was about [with] bringing performance art to the stage. We're doing that again this year with a different performance and I'm so excited with what were doing. It's so me, it's everything I want to say right now. It certainly will be memorable so I hope that the fans will love it as much as we do."
