We're just days away from Lady Gaga's big return to the stage at the 2013 MTV Video Music Awards, and now, the pop star has opened up about what we can expect from her performance!

Gaga, who will be performing her new single Applause live for the first time, told Kiss FM UK:

"Well I don't want to give any specifics because of course I want everyone to be surprised, but it is the most physically challenging performance I've done, ever.

She continued: "It is so beautiful, it is so indicative of me as an artist. I feel in many ways that the performance is like a giant metaphor for me."

The performance at Brooklyn's Barclays Center marks the first time the 27-year-old has wowed the crowd since she [uuid=a6121f60-715d-4b32-b719-88177c7fb68b]underwent major hip surgery[/uuid] at the start of the year.
