On a night that was supposed to be Lindsay Lohan's comeback, the actress reportedly got off to a shaky start during her stage debut in David Mamet's play, 'Speed-the-Plow,' forgetting her lines and unintentionally prompting laughter from the audience. Yikes.

The West End play opened last night (Sept. 24) in London, and the audience watched Lohan anxiously, eager to see her in the role of Karen, a Hollywood secretary with big dreams. According to multiple outlets, it seemed as if the troubled actress had some serious jitters, flubbing her lines as the crew read them to her off-stage.

"Looking pale and nervous, Lohan managed to hang on through her small but critical role as Hollywood secretary Karen — but only with the aid of some crew members offstage who shouted lines at her when she blanked on what she was supposed to say," the New York Daily News reports. Lohan also held on to a prop book that reportedly had some of her lines in it.

The Daily Beast also reveals that the audience openly laughed at Lohan -- laughter that the actress did not intentionally intend to spark.

"On the first night of previews, a work-in-progress feel is to be expected," the Daily Beast reports. "But halfway through the second act of 'Speed-the-Plow,' the audience was openly laughing at Lohan’s struggle to grasp Mamet’s sharp, trademark dialogue."

Still, not everyone was openly mocking Lohan -- some fans loved her performance, or could at least appreciate the fact that she struggled through at the beginning, but ultimately made it work.

We're totally rooting for Lohan, who genuinely must have felt the nerves last night -- it was an enormous moment for her, and a lot was riding on her performance. Opening night is traditionally a little bit rough, and we think that the actress will nail it once she gets more comfortable in the role and back on stage. We have your back, Linds!
