Look out, Chelsea Handler! Lindsay Lohan might be coming for your job.
A vibrant-looking Lohan, fresh off a 90-day court-ordered stint in rehab, filled in for Handler as host of "Chelsea Lately" on Thursday. Although the episode isn't scheduled to air until Aug. 5, from the sneak peek clips provided, it looks like LiLo took the opportunity to poke fun at herself — and fellow actress Kristen Stewart — during her guest spot.
During the episode's round-table discussion, Lohan garnered laughs from the crowd and other hosts when, while reporting on a story that One Direction member Harry Styles is possibly bisexual and dating a DJ named Nick, she deadpanned, "I've been there!" (Lohan dated DJ Samantha Ronson in 2008.)
Lohan also used the opportunity to take a jab at Stewart, who recently made headlines for cursing out a group of paparazzi photographers.
"I'm just excited that Kristen Stewart, you know, finally showed some emotion," Lohan said of the famously indifferent "Twilight" actress.
Her joke garnered a roar of laughter from the audience, and even prompted comedian Fortune Feimster, who was part of the round table, to suggest that her comment may start an alley fight between the troubled actress and the "Twilight" star.
"No, I love her. I'm a Kristen Stewart fan," Lohan insisted before continuing to poke fun at the actress' 2012 cheating scandal with "Snow White" director Rupert Sanders.
