Haven’t had enough of Lady Gaga after “Judas”?  Well now, you’ll finally get to see something that Simon Cowell wanted to happen back when he was a judge on the show!

According to Perez Hilton, both Lady Gaga and Stevie Nicks will perform on the ‘American Idol’ season finale later this month!  There has been no word on any possible Stevie-Gaga duet, but with that kind of star power on one stage, how could there not be?!

And that’s not all Lady Gaga will be doing on ‘Idol.’ According to Ryan Seacrest via Twitter:

“I only have one word for our mentor on @AmericanIdol next week………. Gaga.”

That’s right!  Lady Gaga, alongside her record label boss, ‘American Idol’ in-house mentor, Jimmy Iovine, will be the mentor for the remaining Top 4 contestants Wednesday night.
