Khloé Kardashian has reportedly been ignoring Lamar Odom's calls.

The 29-year-old star split from the NBA player last year after three years of marriage after reports of his alleged infidelity and drug use emerged, and although they're yet to finalise their divorce, she's been refusing to speak to him.

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

The 'Keeping Up With The Kardashians' beauty has been seen on dates with a number of men including rappers The Game and French Montana recently and Lamar is said to be ''jealous'' about his estranged wife's activities.

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 said to be thinking about working on their issues in order to save their marriage earlier this year, but now that they've failed to reconcile, Khloé appears keen to move on.

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