Jane, 68, told Access Hollywood: "I think every once in a while, a very,
very young person who is burning both ends of the candle needs to have
somebody say, 'You know, you're going to pay the piper, you better slow
down.' So I think it was a good thing she got that letter."

Lohan came under fire from James G. Robinson, the CEO of Morgan Creek Production, in July, after she repeatedly failed to stick to her shooting schedule on the film "Georgia Rule."

He said, "We are well aware that your ongoing all-night, heavy partying is the real reason for your so-called exhaustion."

And Fonda, who also stars in the film, hopes Lohan has learned her lesson:

"She's in the magazines, so you always know what she's doing because you can just read about it in the tabloids.

"She parties all the time. ... And you know, she's young and she can get away with it. But, you know, it's hard after a while to party very hard and work very hard.

Fonda, 68, wishes she could wrap Lohan in cotton wool until she is emotionally mature enough to cope with the pressures and temptations which surround her.

She adds, "I just want to take her in my arms and hold her until she becomes grown-up.

"She's so young and she's so alone out there in the world in terms of structure and, you know, people to nurture her. And she's so talented.

"Oh my gosh she can access emotion like nothing. And she just makes me cry. She made me cry a lot and when she was on the set she was really good, it's going to be a good movie."
