Los Angeles: Reality TV star Kourtney Kardashian says she was mean to her younger sister Kim Kardashian when they were children.

"The whole weekend I was really mean to her. I was such a bossy older sister," Bang Showbiz quoted Kourtney as saying.
The 34-year-old has children - Mason, four, and Penelope, 18 months, with partner Scott Disick.
They have another sister named Khloe.
