Get a Sneak Peek at Lindsay Lohan on 'Anger Management' [Video]

Whether you call it a trainwreck or sitcom gold, Lindsay Lohan's hyped-up guest spot on Charlie Sheen's "Anger Management" airs tonight. Lohan, as herself, will play a patient and romantic interest of therapist Dr. Charlie Goodson (Sheen). And as seen in these sneak peeks at the episode -- aptly titled "Charlie Gets Lindsay Lohan in Trouble" -- LiLo's sassy and comedic self-deprecating streak continues. On April 9, she skillfully dodged a series of rehab-related questions (she was court-ordered to enter a facility for 90 days starting May 2) on the "Late Show With David Letterman" by making plucky remarks ("Now you sound like Dr. Phil"), smiling, and playfully rolling her eyes.

In this clip, Lohan -- who just couldn't stay away from Goodson after their romantic evening -- tags along as he conducts a therapy circle with some inmates at a prison. Of course, she's wearing a low-cut floral, knee-length dress with a sexy black swath in back. (What else would LiLo wear to jail?)

One inmate is a die-hard fan: "I've seen 'Freaky Friday' like 400,000 times; let's just get that off the table." But he's more concerned with her eye makeup then her acting career: "How do you get your eyes like that? They always look so twinkly and cute, even with you dragging a--." She suggests eyeliner, but that's not exactly accessible in prison. Sadly for this jailbird, he only has cockroach dust and toilet water. (Gross!) Fun fact: Did you catch a glimpse of the "Family Matters" alum when Lohan walks away? It's Darius McCrary (Eddie Winslow)!

Goodson sends LiLo out, and as she exits, she wryly quips, "By the way, if anybody asks, I was here for the full hour." Seems that art does, in fact, imitate life.

In this additional clip from earlier in the episode, Lohan -- who's wearing nothing but undies and a black T-shirt that reads "Therapists do it on the couch" -- walks up to Sheen with a mug of coffee and seems smitten with the good doc after their night together. When he informs her that he has to go to prison, she asks, "For how long?" He responds, "About an hour." The punch line: "Wow. You have a great lawyer," she says incredulously. Zing (kind of).

On Wednesday night's "The Tonight Show," Sheen finally spoke out on the on-set drama reportedly started by the 26-year-old's penchant for running late. An on-set source had previously said, "From the moment she arrived … she did nothing but hold up the production. She would sit in her trailer and stall, and she delayed until she up and left for her boyfriend's concert... She held everyone hostage."

Sheen confirmed the source's report, telling Jay Leno, "It was as though she had us held hostage, because she gave us half the show. … She was a couple of hours late. She was really not feeling well. We just worked around it," he said, adding with a laugh, "She was late; what can I say?" Hey, at least Day 1 went smoothly.

If you're hoping to see Lohan revive her comedic chops, this episode is likely not going to tickle your funny bone. She is, after all, playing herself, and her role doesn't provide much stretch in the character department. But it's still positive to see the troubled starlet on-screen and not in court.

"Anger Management" airs Thursdays at 9:30 PM on FX.
