Kim Kardashian has supposedly asked Kanye West to reveal all the women he's ever been with.
The engaged couple are set to walk down the aisle on May 24, in a ceremony held in Paris.
But before Kim takes her vows, friends say she she'd like to know every last detail of Kanye's dating history.
"Kim's life has been an open book - everyone knows everything about her marriages and men. But there's so much she doesn't know about Kanye. So now she's demanding he confesses all," an insider divulged to British magazine Now.
The source went on to reveal that the pair, who have been an item since April 2012, decided to have a heart-to-heart recently where Kim opened up to Kanye about her notorious sex tape with ex-boyfriend Ray J.
She also discussed her relationship with American football star Reggie Bush, but Kanye reportedly wasn't keen to reciprocate the honesty.
"When it was Kanye's turn, he quickly decided he'd had enough," the insider added.
Allegedly Kim wanted to know details about Kanye's past rumoured flings with Rihanna, Nicki Minaj and Iggy Azalea, but the 36-year-old rapper wasn't playing ball.
"He flipped out. He told her that while he had nothing to hide, it was none of her business," the insider continued.
Instead of focusing on the past, Kanye wants to concentrate all of his efforts into his union with Kim.
It's rumoured that he's even hired a tantric sex therapist to spice up their love life following the birth of the couple's first child, daughter North, last June.
"It's more like a yoga session mixed with couples' therapy. There are loads of breathing exercises.
"Tantric sex may solve all his problems," the source stated, in reference to Kanye's recent court ordered anger management sessions.
