(Cover) - EN Showbiz - Kourtney Kardashian has admitted she was nervous about shooting a kissing scene for One Life to Live.

The reality TV stars acting debut will be unveiled on March 28, when she appears as lawyer Kassandra Kavanaugh in an episode of the long-running US soap opera.

The 31-year-old adapted well to her new career venture, although she admits there was one aspect of the job she didnt enjoy so much.

Kourtney is mother to 14-month-old Mason, her son with partner Scott Disick, and she admits she wasnt too keen on filming steamy scenes with David Fumero - who portrays bad boy Cristian Vega.

"That made me nervous," she blushed in an interview with UsMagazine.com.

"But after the kiss, he was like, 'I can't remember my line!'"

Kourtney is excited about her role in the daytime show which first aired in 1968 and has always been a massive fan. The star even confessed to pretending to be ill as a youngster so she could take the day off school and watch it.

"Growing up, I would always pretend to be sick so I could stay home from school and watch One Life to Live!" she laughed.

"It was so much fun!" (C) Cover Media
