Rob Kardashian puts his fiance Blac Chyna on a pedestal, but no one has a problem with that. This week, though, he basically put his unborn daughter on a crucifix, and people are having a real problem with that.

Rob posted a photo of his baby mama in a nativity scene, substituting Mary, the mother of Jesus, with a photo of a pregnant Chyna from her recent Paper magazine spread.

He commented on the image using emojis indicating he was laughing. Chyna commented, as well, with a laughing emoji.

For many Christians, this was no laughing matter and they came out attacking the reality star for comparing his daughter to Jesus Christ. Rob, as he often does, deleted the picture as many criticized him for the post. (MTO has a screen grab of the image.)

The couple is certainly no stranger to controversy. Even Rob's famous family was irked when he began dating the model and mother to King Ciaro, whom she shares with Tyga, Kylie Jenner's boyfriend.

The family has come around and accepted her. But still, it hasn't been easy sledding for the couple. In mid-August a preview for their upcoming reality show "Rob & Chyna" was released and it showed the two in an explosive fight.

The clip hinted that the reason Rob deleted all of his Instagram photos, including those of Chyna, in July was because of other women.

"I fell in love with you because I know how good you are and how loyal you are," Rob started out telling his fiance in a scene.

The drama quickly intensified in a new scene with the pregnant bride-to-be questioning her man. "Are you still texting b----es, yes or no," she yelled.

The preview also showed her angrily chucking a bouquet of flowers into the pool and locking Rob out of the house.

Their dramatic fights will apparently be the center of the entire series.

But, there were a lot of sweet moments from the lovebirds, too. The clip showed the duo laughing together and showing some major affection.

At one point Blac Chyna asks Rob if he's ready to be a daddy while he rests on top of her belly. He sweetly replied, "That's what I've always wanted."
