United Kingdom, Dec. 4 -- Kim Kardashian changed her name just before making her debut on Keeping Up with the Kardashians.

The 45-year-old star formerly went by her full name Kimberly Kardashian but made a last-minute change before the show first aired in 2007 as she realised it was too long when seeing it on screen.

Kim told Time magazine: "I used to always go by Kimberly, until we signed on to do the reality show.

"I said, 'I think that's so long for people to say.' And like, 'Let's just shorten it to Kim.'

"And it's so weird, because all my friends from high school and growing up, and my dad, everyone calls me Kimberly."

The All's Fair actress also claimed the credit for persuading her sisters Kourtney Kardashian, Khloe Kardashian...
