Rocker Stevie Nicks insists she'll never give Lindsay Lohan the OK to play her in a biopic - until she proves her worth as a serious actress.
Lohan has expressed an interest in portraying the Fleetwood Mac singer, but Nicks wants the actress to prove she's no longer a mess first.
The singer tells CNN.com, "That's never going to happen unless she cleans up her life and becomes the great actress I feel she can be."
But Nicks insists that doesn't mean she's not a fan of the Mean Girls star, who has spent the last 18 months jumping between jail and rehab after a series of personal lows.
She adds, "Everybody thinks I hate her, and it's not that at all. I just want her to get it together.
"I was completely messed up for a long time and I got it together. She's a very talented girl... If she could get it together, she could have a really big career and she could do great things."
