Tell all tome: Ray J makes the allegations in his new book Death of the Cheating Man
Kim, who was spotted out looking at locations for a new DASH clothing store in West Hollywood earlier this week, was married to music producer Damon from 2000 to 2004.
She is said to have made the sex tape with Ray back in 2003 before it was leaked in 2007.
Life & Style say that Ray claims 'KK pursued and slept with him while she was still married to her first husband.'
'To be honest, the whole thing started off wrong,' writes Ray J, who was last romantically linked to Whitney Houston before her death.
'We'd known each other for a while before we dated and there was a mutual attraction, but she was married.
'She let me know she wanted to get with me. She left her husband for me as soon as we started having sex and things between us got intense really fast. After that, I felt obligated to be with her.'
Claims: Ray cryptically alleging that she cheated on her first husband Damon Thomas with him
A spokesman for the star had no comment on the latest claims.
But an friend close to Kim told MailOnline: 'It's absolutely ridiculous.
'Kim actually feels bad for him for making a reference to a relationship that ended many, many years ago in order to sell books.
'She never cheated on him, but it looks like he’s making this up to make himself feel more at peace for all the cheating HE did.'
Ray J also goes onto reveal details about the intimate side of their relationship.
'We were like animals; sexually free to try anything, and we did,' he writes in the book.
'For years KK and I had a great sex life. There was more to our relationship, but the majority of it was about our wild and extreme sexual chemistry.

He adds 'She literally thought I was cheating with every girl I ran across.'
Kim has yet to comment on her ex boyfriend's allegations, but a source told Life & Style that she is 'furious about Ray J cashing in on her.'
The insider added: 'There's so much that has gone wrong for her this year - he's just another person trying to humiliate her.'
