Khloé Kardashian is reportedly refusing to speak to Lamar Odom.

The 'Keeping Up With the Kardashians' star split from the NBA player last year amid claims he cheated on her and became hooked on drugs and, although she still needs to finalise her divorce, she's currently rejecting his calls.

A source told RadarOnline: ''She's been refusing to take his calls recently.''

The 29-year-old stunner, who filed for divorce in December after four years of marriage, has been spotted with a number of men recently - including The Game and French Montana - and it's believed Lamar is getting ''jealous''.

The source explained: ''Khloé is out in public with new guys all over them and it is killing Lamar. Yeah, he was totally with other women first, but he doesn't want Khloé to shove it in his face that she is moving on. Lamar is jealous and gets mad when she refuses to talk to him.''

The former couple were initially determined to work on their issues and save their marriage but, after they failed to reignite their romance, Khloé is now keen to move on.

The curvaceous brunette has just moved into Justin Bieber's former home in Calabasas, California, after selling her former marital home in nearby Tarzana to Kaley Cuoco.

The source added: ''Lamar and Khloé are done. He tried and she tried but now there's nothing to go back to.''
