"I think Bono or Bon Jovi or Mick Jagger. You know me, I think big," Lopez told ABC news.

The 42-year-old also says leaving of co-host Steven Tyler inspired her to leave the show.

"We had magic. I don't know, with him gone, it might be a different formula," she said.

Lopez announced her departure last week after two series of the show.

Rumours are abuzz that singer Mariah Carey will take Jlo's place but nothing has been confirmed. Recently actor Charlie Sheen also showed interest in judging the show.
