Lindsay Lohan has been ordered to gain weight and undergo drug testing by the producers of her upcoming film, The Other Side.

Lindsay has such a poor reputation on the Hollywood scene for wildchild misbehavior and diva antics, the only way the former child star could be hired for the film was to agree to gain weight, attend weekly weigh-ins, adhere to a nightly curfew during filming, and undergo random drug and alcohol testing.

The makers of the upcoming motion picture thriller are familar with Lindsay’s binge drinking and multiple trips to rehab, and insiders say they aren’t taking any chances that LiLo will suffer one of her famous relapses at their expense.

“Producers want Lindsay looking like a normal, healthy girl, not a skeleton,” a production insider tattles in the June 7 issue of Star, adding: “So they ordered her to rest up and eat more. They refuse to risk her dropping out of the movie because of her problems.”
