Khloé Kardashian's family are reportedly ''very concerned'' she'll rekindle her romance with estranged husband Lamar Odom.

The 30-year-old reality TV star has recently sparked rumours she's seeing the 35-year-old basketball player, who she filed for divorce from in December 2013, again and her relatives - including sister Kim Kardashian West - are reportedly worried he'll hurt her again.

A source told RadarOnline.com: ''Her sisters, and entire family, care for Lamar a great deal because he was there since the beginning. But everyone is also very concerned because they do not want to see Khloé go through what she went through already with him prior to her decision to file for divorce. He tore her down and it has taken her so much to get back up.''

The 'Keeping Up With the Kardashians' star called time on her three-year marriage in September 2013 following rumours her spouse had cheated on her with numerous women and had an addiction to cocaine but, despite filing for divorce over a year ago, the legal proceedings to annul their marriage is still ongoing.

Following their split, Khloé struck up a relationship with rapper French Montana last year but their romance was short lived because the brunette beauty didn't feel ready to move on.

However, the former pair, who split last November, have recently been spotted with one another and have sparked speculation they could be dating once again.
