Lindsay Lohan pokes fun at Kristen Stewart on TV

Lindsay Lohan kicked off her guest-hosting stint on late-night comedy and chat show Chelsea Lately by poking fun at Kristen Stewart.

The Mean Girls star, who ended her 90-day, court-ordered stint in rehab earlier this week (30Jul13), taped her appearance on the program as vacationing host Chelsea Handler's stand-in on Thursday (01Aug13), and in a teaser clip posted online, she takes aim at the Twilight star.

Discussing the actress' altercation with a paparazzo while walking her dog earlier this week with a panel of comedians, Lohan quipped, "She said, 'You're a piece of s**t. You don't deserve to breathe the same air that I do.' I'm just excited that Kristen Stewart finally showed some emotion."

As the studio audience whooped and cheered, Lohan insisted, "I think she's awesome," and added, "I'm a Kristen Stewart fan," before stating, "I will say this, of course she hates photographers - they caught her kissing a married man in a Mini Cooper."

Stewart's romance with Twilight co-star Robert Pattinson ended last year (12) after she was caught in a car park clinch with her Snow White & The Huntsman director Rupert Sanders.
