Kris Humphries' ex could help Kim in divorce battle

Kris Humphries' ex-girlfriend is set to help Kim Kardashian in her divorce proceedings against the basketball star.

The athlete is currently involved in a battle divorce battle with the reality TV star - following the breakdown of their 72-day marriage in October - and now his former flame Myla Sinanaj is threatening to hand over vital information to Kim.

Myla's attorney, and former prosecutor, Joe Tacopina, told RadarOnline.com: "My client isn't going to rule anything out at this point including whether or not she would be willing to assist Kim Kardashian in her divorce case. I will say this, Kris Humphries has to be the only 7ft man in the universe to have two women under 6ft tall bully, defraud and attempt to extort him. It's absolutely ridiculous."

Earlier this week, Myla demanded Kris apologise for trying to destroy her reputation.

Tacopina suggested the NBA player had gone on a campaign of destruction against her to make himself look better in his divorce court battle.

It recently emerged that Kris' lawyers had contacted the FBI, claiming Myla tried to extort him by demanding a huge sum of money or she would spill secrets about their relationship to the media.

Joe told TMZ.com: "I defy them to show that she has asked for one red cent. I challenge them to submit Kris Humphries to a polygraph and if he does I will have my client do the same. She never asked him for a penny."

Myla's team also hit out at claims she was never his partner.

Her legal representative said: "I have hundreds of text messages and phone records which show he constantly contacted her on a steady basis. He'd call her 50 times in a day."
