Lady Gaga designs her own stage for Las Vegas pop festival

Lady Gaga has added set designer to her impressive resume after creating the stage she'll perform on at the I Heart Radio Festival in Las Vegas this weekend (24Sep11).

The pop superstar will headline the MGM Grand event and she gave host Ryan Seacrest a taste of what to expect during a radio chat on Friday (23Sep11).

She says, "I designed the stage especially just for this one performance; it will never be used again. When you see what I've built it will be really exciting.

"I know I'm only supposed to play really for 45 minutes but, because I'm the last act, I think I might play for a bit longer.

"I filmed some new films for it... and the choreography and (I have) special custom costumes from Versace.

"I'm going to make everyone scream their heads off."

The two-day event, which will also feature performances from the Black Eyed Peas, Alicia Keys, Jay-Z, Jennifer Lopez, Carrie Underwood and Coldplay, will begin on Friday night (23Sep11).
