Scott Disick has reportedly made ''eight or nine'' sex tapes.

The restaurant owner - who is expecting his second child with Kourtney Kardashian - used to be a party animal and womaniser and before settling down with Kourtney he and his friends would bed lots of girls and sometimes film their antics.

His friend Donald told Life & Style magazine: ''Scott was obsessed with sex. We'd bring back different groups of girls to one of our houses and do various things to them. We tried to make it a daily routine, and some nights would be taped. There's probably eight or nine tapes.''

Donald says he and Scott - who stars in 'Keeping Up with the Kardashians' with Kourtney and her family, including sisters Kim and Khloe - decided to film themselves as they wanted to become famous.

He said: ''We thought if we started videotaping ourselves, maybe one day we can make a TV show out of it. Now Scott's on a reality show. He was always trying to make it to the top.''

He also confessed that the women involved in the antics were often drunk and high on marijuana.

Scott and Kourtney already have two-year-old son Mason and are set to welcome a daughter next month.
