Lindsay Lohan's pal believes she can "turn it around" if she "gets help".
The troubled star was recently sentenced to 90 days in rehab after pleading no contest to misdemeanour charges of reckless driving, lying to authorities and obstructing police from performing their duties.
She has until May 2 to check in, leaving her free to attend music festival Coachella, which runs from April 12 to 21.
Lindsay has been a regular at the event since 2010, but pal Claus Hjelmbak thinks she should give it a miss this year.
“Lindsay is in a very dark place right now, and I’m absolutely scared for her life. Coachella is the last place she needs to be," he sighed to RadarOnline.
"For someone struggling with addiction, like Lindsay, the amount of drugs and alcohol at Coachella is just a recipe for disaster waiting to happen. I know because I have been to the VIP tent at Coachella in the past. Lindsay can turn it around, but she has to look deep inside herself and get the help she needs."
The 26-year-old actress has been displaying some erratic behaviour recently and apparently vomited while filming a scene for Charlie Sheen's Anger Management TV show.
Echoing Claus' fears, Lindsay's father Michael Lohan recently expressed concern his daughter could join the likes of Amy Winehouse and Kurt Cobain and pass away at the age of 27.
Claus thinks his famous friend should spend time with her family rather than pals who could be using her.
“The people associated with Lindsay right now are a very bad influence on her. They are only using her because they love to be around a celebrity. Lindsay needs to cut off ties with these losers because they are bringing her down," he sighed.
"I may have had my differences with her father, Michael, but at least he is trying to do something to help her. Lindsay’s father is the only person trying desperately to help his daughter, he gets it."
