Jenni Muro, who works for the 'Mean Girls' star, told Lohan's father Michael in a phone call that the actress will commit suicide if she doesn't get the help she needs, Radaronline reported.

"I am trying to save your daughter's life every day. She is another mess, she's no better than she was two years ago and she knows that. If I wasn't around she would be in grave danger," Muro told Lohan's father.

"I gave up everything, my boyfriend and my dog and my parents and my new place in LA, everything just so your daughter doesn't kill herself," she said.

Muro also told Michael about Lohan's obsession with her on/off lover DJ Samantha Ronson, but assured him that Lohan has no other problems with addiction.

"It's an unhealthy relationship with Samantha because I don't ever think she knew love before and this is what she thinks it is, maybe it maybe it isn't, I don't know but it's her only addiction right now."
