Lohan, 27, mocked Stewart's latest run-in with a papparazzo on Chelsea Lately.
Stewart, 23, had yelled at a photographer for clicking her pictures, reported Us magazine.
"I'm just excited that Kristen Stewart, you know, finally showed some emotion," Lohan quipped before adding, "No, I really do love her. She's awesome. I'm a Kristen Stewart fan."
But that didn't stop her from taking another dig at the 'Twilight' star.
"I will say this, of course she hates photographers -- they got a picture of her kissing a married man in a Mini Cooper," she added, referring to Stewart's cheating scandal with her "Snow White and the Huntsmen" director Rupert Sanders last year.
Lohan has her own troubles to worry about. The actress is trying her best to make a comeback post her court mandated rehab stint. She still needs to complete an additional 15 months of psychological therapy.
