(Yahoo!) - Fresh off a court-ordered 90-day rehab stint (which she has insisted was basically unnecessary), Lindsay Lohan returned to the spotlight — in late night. "The Canyons" star stood in for funny girl Chelsea Handler to host "Chelsea Lately." And you know what? She did a pretty awesome job.

Rocking skintight black pants, fiery red locks, and a gold cross necklace, the 27-year-old actress kicked off the show with a special thank you.

"I'd like to thank the celebrities who kept the tabloid industry alive in my absence," she cooed with a smile. Included on her list were New York mayoral candidate Anthony Weiner, new dad Kanye West, badly behaving Justin Bieber, and, finally, the royal baby.

Looking positively luminous, Lindsay assured the audience, "I'm back. I'm happy. I'm healthy. And I'm sorry paparazzi, but you want to take pictures of someone who's really f----d up, you're just going to have to wait until Chelsea's back."

But Lindsay did more than show up, look good, and deliver some zingers. She instantly gelled with her comedy panel and even managed to inject some personal commentary into the discussion without taking it over.

When discussing the first story, which happened to be about Harry Styles having a possible sexual relationship with a gay DJ, Lindsay quipped, "I've been there." And later, when the focus turned to Kristen Stewart screaming at a photographer who had been following her, Lindsay noted, "I'm just excited that Kristen Stewart finally showed some emotion." In other words, Lohan's got jokes, including a few about herself.
