(SoapOperaNetwork.com) — Entertainment Tonight gives viewers a sneak peek at reality TV socialite Kourtney Kardashian‘s March 28 appearance on “One Life to Live,” in which the heiress admits it was “definitely a lot more than I thought I was agreeing to.”

The clip, from this Sunday’s episode of “Kourtney & Kim Take New York,” shows just how worried Kardashian was about memorizing her lines for the soap, in which she will play attorney Kassanda Kavanaugh, telling her sister Kim and boyfriend/baby daddy Scott Disick, “I literally thought I would have two lines and my script is so long.”  The apprehension soon spills over to the set when she went to tape her scenes (back in November), much to the apparent frustration of “One Life’s” Executive Producer Frank Valentini.

Kardashian also expresses hesitation at having to kiss David Fumero (Cristian Vega) on screen.  “I’m not an actress.  I just don’t feel like kissing some random guy.  There’s no way I could kiss that face,” she states after looking up Fumero’s picture online.

Be sure to watch “Kourtney & Kim Take New York” Sunday night at 10:00 pm ET on E! for more Kardashian drama as she takes both New York City and Llanview by storm.
