Reports are circulating that American reality TV star Khloe Kardashian is pregnant.

According to the 13 October issue of OK! Magazine, the 30-year-old is expecting a baby with estranged husband Lamar Odom.

The Keeping Up With the Kardashians star had filed for divorce from the 34-year-old professional basketball player on 13 December after four years of marriage, citing irreconcilable differences.

By April, Kardashian started dating French Montana. However, it was recently reported that two have split.

"Those close to Khloe think she could finally be pregnant," an insider told the magazine. "All she ever wanted was to have a baby with Lamar, and if her wish is actually coming true, she'll know their love was meant to be."

"Khloe's been acting very strange over the past month, refusing alcohol and ditching activities with friends and family because she says she doesn't feel well," the source added. "Even though she hasn't told anyone that she's pregnant, it's no secret to her loved ones that she's seeing Lamar."

Kardashian and Odom's marriage first reportedly hit the rocks when a video surfaced showing him rapping about how he cheated on her. He was also allegedly not willing to take professional help for his drug addiction.

Odom has been reportedly trying to win her back for a few months.

"Lamar apologised profusely for the past and didn't hold back his feelings, leaving Khloe convinced that he's a changed man," an insider said.

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

During an interview with Billboard, French Montana, whose real name is Karim Kharbouch, revealed that he was getting extra attention from the media after he started dating Kardashian.

"I want to capitalise on it," Montana said. "I'll get a fan base from everywhere. I just hope I'll be able to connect with everything that's going on," he added.
