Lindsay Lohan mocks Kristen Stewart on 'Chelsea Lately'

Lindsay Lohan quipped like a natural-born talk-show host Monday night guest-hosting E!'s "Chelsea Lately."

"Kristen Stewart told off paparazzi this week," Lohan said during the roundtable segment, reading from an index card and describing how the "Twilight" star cursed at photographers, telling them, "You don't deserve to breathe the same air that I do." Quipped Lohan without missing a beat, "I'm just excited that Kristen Stewart finally showed some emotion."

Lohan, 27, showed equally impeccable timing while reading an item about One Direction boy-band singer Harry Styles, who recently did a magazine interview in which "he was questioned about rumors that he's bisexual with a DJ named Nick. I've been there," Lohan said with a smile, seemingly off the cuff and to audience laughter.

Continuing, she quoted Styles telling the interviewer, " 'I've only ever had sex with two people,' -- Yeah, he's never hung out with The Wanted," she added about another, evidently more worldly boy band -- and then tacked on a comically vulgar addendum, prompting more laughs.

Also Monday, OWN released the first clip of Oprah Winfrey's upcoming interview with Lohan. "Are you an addict?" Winfrey asks the actress, following up with, "What does it feel like to be both an adjective and a verb for child-star-gone-wrong?"

The teaser clip showed no response from Lohan, who wore a bright orange dress with her hair pulled back. The interview was taped after Lohan's release from rehab last week and will air Aug. 18.

Winfrey also discussed the interview during an appearance Monday on "CBS This Morning," describing Lohan as "honest, authentic and ready."

Additionally, TMZ.com said Monday that Winfrey had dissuaded the actress from taking a planned three-week European vacation scheduled to start this past Sunday, convincing Lohan that such a trip so soon after rehab could threaten her sobriety.
