American reality television star Khloe Kardashian reportedly wants estranged husband Lamar Odom to sign their divorce papers, but she can't get hold of him.

The 30-year-old Keeping Up With The Kardashians star filed for divorce from Odom in December 2013 after four years of marriage, citing irreconcilable differences.

The couple's marriage first hit the rocks following the publication of a video showing Odom talking about how he cheated on his wife. He was also allegedly not willing to take professional help for his drug addiction.

"He [Odom] needs to sign papers and he won't. He disappears here and there, and she can't find him. She [Kardashian] just wants to move on," a source told People.

Kardashian started dating rapper French Montana in April. However, it was reported that the two have since split.

Recent reports stated that Kardashian and Montana's relationship was a publicity stunt for the cameras and that Kardashian matriarch Kris Jenner paid the Moroccan-born musician to appear on the family reality show.

Amid these reports, Hollywood Life claimed that Kardashian wants to find fresh love and start a family.

"She wants to be in love again," a source told Hollywood Life. "She wants a family. She doesn't want to be pigeonholed as the best aunt in the world.

"She loves her nieces and nephew but there's nothing like being a mother. She wants that. And it's like, 'here she goes again being the dutiful and proud aunt.'

"She's happy for Kourt and Kim [Kardashian] but she's sad inside because everyone around her is thriving and living and she's stuck. Her life sucks right about now."
