Khloe Kardashian is reportedly going to be a mom! But who's the father: her estranged ex-husband Lamar Odom or ex-boyfriend French Montana?

Sources close to the 30-year-old "Keeping Up with the Kardashians" told OK! magazine in its Oct. 13 issue that she might be pregnant with Odom's baby.

"Those close to Khloe think she could finally be pregnant," an insider revealed to the British weekly magazine, as quoted by Hollywood Life. "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."

Kardashian's pals think that she could be carrying Lamar's baby because she is said to be acting weird and seeing the 34-year-old basketball player lately.

"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 tipster explained. "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 tied the knot in Sept. 2009, according to People.

But in December last year, after months of speculated separation, Kardashian filed for divorce from Lamar, and for legal restoration of her last name, Fox News reported.

But now, Odom is reportedly doing his best to win her estranged wife back. OK! magazine even claimed that the former New York Knicks player wrote a very heart-felt letter to Kardashian.

"Lamar apologized profusely for the past and didn't hold back his feelings, leaving Khloe convinced that he's a changed man," OK! magazine's source dished.

Meanwhile, Kardashian is said to have totally moved on from her relationship with Montana, whom she split with after discovering that he had been hitting on her best friend Malika, Inquisitr reported.

It is believed that Kardashian's split from Montana paved the way for Odom to try and win her back for good.
