The basketball star had claimed to be ''devastated'' when the reality TV beauty filed for divorce after just 72 days of marriage in October but Myla Sinanaj - who has been subpoenaed by Kim to testify in their divorce case - reportedly has several text messages in which her then-lover says she is the love of his life.
According to gossip website TMZ, some of the messages from Kris state he wants his divorce from Kim to be over with so he can spend the rest of his life with Myla, who he began dating in January.
The information could be damaging for Kris because he has alleged in his divorce papers that he was left ''emotionally devastated'' by the split and he believes he was defrauded by Kim into thinking they had a ''real marriage''.
The website also claims that Kris told Myla that Kim's infamous sex tape with former boyfriend Ray J was shot under the guidance of her mother Kris Jenner and the showbiz matriarch even ordered it to be re-shot because it wasn't ''pretty enough''.
However, sources close to Kim insist that she always refused to discuss the raunchy film with her estranged spouse because she didn't want to be judged by it.
Kim's sister Khloe also hit out at the claim, blasting it as ''disgusting''.
She said: ''That is just disgusting and disturbing, and probably his fantasy!''
