Madonna will sing 'Like A Virgin' for $30m

Madonna is only prepared to sing her classic hit singles 'Holiday' or 'Like A Virgin' if someone pays her $30m!

"I'm not sure I can sing 'Holiday' or 'Like A Virgin' ever again," the singer tells New York's Z100-FM in an interview scheduled to air Friday. "I just can't – unless somebody paid me like $30 million or something. [Like if] some Russian guy wants me to come to the wedding he's going to have to a 17-year-old, you know it."

As the 49-year-old superstar gears up to release her latest album, Hard Candy, on April 29, Madonna also dishes the dirt on the music business: "Playing live is not something that people focus on very much," she says.

She also revealed why she gave Justin Timberlake that now-infamous B-12 shot in the rear end while working on her new album. "First of all, I've seen enough butt ... The reason I gave him a B-12 [shot] is because we only had a certain amount of days in the studio and I didn't want him to use that as a lame-ass excuse not to come to work. Okay? It's got nothing to do with butt. I promise you. Listen, I don't need to give him a shot to see his butt. Duh."

And on Britney Spears' new record 'Blackout', she said, "I actually love Britney Spears's new album ... I usually work out to her record. I do a combination of pilates and dance aerobics."

And if she were a contestant on American Idol?: "I went to a lot of auditions for musical theater and conventional mainstream things – and I always got cut immediately. So I'm pretty sure the same thing would happen to me."
