Socialite Khloe Kardashian works quickly. The 32-year-old sports groupie is reportedly knocked up by NBA star Tristan Thompson!

X17online.com reports exclusively that Kardashian is having Thompson’s baby.

The 25-year-old Cleveland Cavaliers star is also expecting a baby with his ex-girlfriend, seek Jordy C, whom he dumped when he met Kardashian at Kevin Hart‘s wedding.

Kardashian was spotted arriving at LAX airport on Wednesday, Nov. 2, wearing a black sweatshirt to conceal her growing baby bump.

She flew back to Los Angeles to pack her things for the cross country move to Cleveland to be closer to her baby daddy.

It is indeed a modern day miracle if this report is true. Rumor had it that Kardashian was barren and unable to conceive.

A source tells X17online exclusively:

“Khloe is SO happy. The pregnancy came as a surprise, particularly since Tristan’s ex-girlfriend is currently pregnant, but Khloe got on board with the idea of having a baby pretty quickly.”

And get this — her NBA star beau plans on flying into town this weekend to ask Kris Jenner for Khloe’s hand in marriage! True to form, though, the momager knows all about the plan and has already purchased a Range Rover for Thompson as a “welcome to the family” gift. Our source tells us: “Khloe and Kris want everything done correctly. They don’t want this to look like an accident and Khloe really wants to show the world that Tristan is her man. She wants to kind of follow tradition and have Tristan ask her mom for permission to propose, in hopes of making the engagement look more traditional and formal.”
