If you're Kourtney Kardashian, you don't just sit at home watching your favorite soap opera – you star in it
The eldest Kardashian sister lived out a lifelong dream when she made her debut on the ABC soap One Life to Live
as Kassandra Kavanaugh, a wayward lawyer with a knack for trouble.
While Kardashian, 31, is no stranger to cameras or drama, memorizing her script – as documented on her reality show Kourtney and Kim Take New York
– was a struggle.
"I'd thought I'd have two lines," the reality star said. "But my script is so long ... I'm not an actress."
Fortunately, Kardashian's scene proved to be deliciously campy, thanks in part to her costar, OLTL
's David Fumero and another guest star, Wendy Williams.
The current Dancing With the Stars
contestant played news anchor Phyllis Rose on the mock local news show Access Llanview
Williams introduced Kardashian as "none other than local ambulance chaser Kassandra Kavanuagh. That's right," she said, "with two Ks."
One Life to Live
airs Monday through Friday (2
p.m. ET) on ABC.
