Khloe Kardashian has reportedly filed for divorce from husband Lamar Odom today after four years of marriage.

The couple have been battling divorce rumors for some time, especially after a woman came forward claiming to have had an affair with Odom…and that they were busted in the act by Khloe.

“I was under the impression that he had left Khloe … he acted completely available and we definitely had a mutual attraction,” Polina Polonsy said. “After we had sex, Lamar stayed the night with me; the next day we went back to the Roosevelt. I stayed there with him for the next couple of nights.”

Odom reportedly went missing over the summer after running out on an intervention Khloe and her family staged for him, and rumors of crack addiction ran rampant. He was also arrested in August for DUI, and entered a no-contest plea earlier this month in exchange for 3-years of probation and an alcohol education class, plus various fines.

Odom released a bizarre video of himself free-styling about cheating on Khloe recently, which may have been the straw that broke the camel’s back.
