Kim Kardashian could be forced to relive her past as her sex tape making ex-boyfriend Ray-J is said to be entering the Celebrity Big Brother house.

Kimmy K, 36, owes her fame to the sex tape she made with Ray, 35, back in 2003.

The tape leaked in 2007 kick starting Kim’s headline grabbing career and producers of CBB are hoping Ray-J will spill all the details as a member of the reality show house.

“Bosses are over the moon with how the negotiations are going,” a source told The Sun.

“Kim is one of the biggest celebrities in the world and they were never going to get her but booking Ray J means they’ll get someone with proper insight into what goes on behind closed doors,” the source added – even though the tape kind of displayed what goes on behind said closed doors…

“He was right by her side as she shot to fame because of their sex tape so they are hoping he will talk openly about their relationship and reveal lots of new things about her while in the house,” the source continued.

Kim and Ray-J dated for three years before splitting - with Ray since finding love and marrying Princess Love while Kim is currently married to her third husband, Kanye West.

Whether or not we get to hear about Kim’s dirty laundry via Ray-J will be seen on January 3 when Celebrity Big Brother returns to Five.
