Khloé Kardashian is back in contact with Lamar Odom.

The 'Keeping Up with the Kardashians' star reportedly reached out to her estranged husband - whom she filed for divorce from in December - following her recent split from rapper French Montana.

A source told In Touch Weekly magazine: ''After months of not talking, she's been calling Lamar. Ever since the split, Khloé's been super sad and really missing Lamar, so she decided to reach out. Lamar was so happy to hear from her.''

The couple, who were married for four years, split following months of revelations the NBA star was taking cocaine and cheated on the 30-year-old reality TV star multiple times.

Despite what has happened between them, Khloe still has feelings for basketball player Lamar.

The source added: ''Khloé will always love Lamar, even after all the things he has done to her. She blames it on his addiction.

''Lamar will always want Khloé back. It's sad to say, but I wouldn't be surprised if they got back together.''

Khloé dumped French, 29, whom she began dating eight months ago, because he had become too ''needy'' and ''dependent'' on her.

A friend recently said: ''They are on a break. The relationship got too heavy and Khloe needed to take a step back.''

Another source added: ''It grated on her that he became so dependent on her.''
