Kourtney Felt "Like A Prostitute" On OLTL

Kourtney Kardashian is ready to kiss and tell.

Days after making her TV acting debut on One Life to Live, the reality star says she's still reeling over her big on-screen smooch.

"I felt like a prostitute," the 31-year-old mom admitted to Jay Leno during a Thursday appearance with sis Kim. "Like, [I was] being paid to kiss someone."

While Kardashian's beau of nearly four years, Scott Disick, helped her practice her kissing scene, the newly-minted actress says it took her a while to warm up to her OLTL costar David Fumero.

"I looked him up online," she told Leno of Fumero, who appears as bad boy Cristian Vega. "I'm like, 'I need to see this guy. Is he 99 [years-old], like, what is he?' And he's a very handsome guy. So that makes it easier."

When it came time for the big moment, Kardashian was prepared. "I probably ate a hundred mints that day," she tells Leno. "But I'm still such a prude!"

All in all, the Kourtney and Kim Take New York star was happy with how her episode turned out.

"Growing up, I would always pretend to be sick so I could stay home from school and watch One Life to Live!" she tells UsMagazine.com. "[My role] was so much fun!"

Kourtney & Kim Take Leno's 'The Tonight Show'

Looking to satisfy their growling tummies, Kourtney Kardashian and sister Kim Kardashian were spotted hitting up Mr. Chow restaurant last night (March 31) following their interview with Jay Leno.

During her interview on the “Tonight Show,” Kim told Jay Leno that her boyfriend Kris Humphries helped her get over her fear of tall people.

"I was really afraid of [tall guys]. I'm, like, the biggest hypocrite now, 'cause now I feel so tiny and small and so protected. It's like the best feeling in the world to be with a really tall guy."

As for how they met, she explained, "I went to a basketball game. I saw him and I was like, 'Oh my God, this guy running in front of me is so cute.' And my friend was like, 'Oh, I know his friend.' So they kind of set us up on, like, this group dinner and I thought, 'Why not?'"
