Producers on the set of Lindsay Lohan‘ s new movie Labor Pains say so far she’s earned high marks for professionalism, as she gets her film career back on track. “We were a little bit reluctant to work with her,” Lati Grobman, one of the producers, told People magazine. “But she’s been amazing.” Lohan has been plagued by one box office bomb after another, as she struggles to overcome drug and alcohol problems. In her new movie, Lohan returns to the comedy roots that made her famous, playing a publishing house employee who escapes getting fired by pretending to be pregnant. Lohan has actually been showing up early to set, but like many young celebs, continues to be hounded by paparazzi. “I’m not a producer anymore, I’m a police woman,” says Grobman.
