Kim Kardashian West and her mother deliberately leaked her sex tape to make her famous, a new book has claimed.
The 35-year-old reality star signed a contract with Vivid Entertainment in 2007 to leak the raunchy film she made with then-boyfriend Ray J in 2003 after being "advised" by a friend it would be a quick way to find fame, and allowed her mom and manager Kris Jenner to finalise the deal that led to the footage being made public.
