The arrival of a new baby should be one of the happiest moments on earth. Bringing a new life into the world is an incredible experience, and shouldn't be overshadowed by anything else - unless the father of your child has cheated on you days before you're expected to give birth.

While it seems like an unfathomable situation, Khloe Kardashian, 33, is experiencing just that. On April 10, it was exposed that her baby daddy Tristan Thompson, 27, cheated on her right before her due date.

After months of speculation, Khloe finally announced she was pregnant with Tristan's child in late December. Even though the couple posted several photos on social media to document their fairy tale bliss, Tristan was keeping something from the world - his wandering eye.

Allegations of Tristan's infidelity spread after he was seen at PH-D Lounge New York City, celebrating his basketball team's victory. In a video obtained by the Daily Mail, the Cleveland Cavaliers player is seen kissing a brunette at the nightclub. TMZ later acquired footage of Tristan and the woman, later identified as Lani Blair, entering the Four Seasons Hotel at 5 a.m.

While Tristan was out messing around with another woman, Khloe was in Cleveland, Ohio, where she announced she would give birth.

He's a "serial cheater"

Sadly, this isn't the first time Tristan has cheated on the reality star. Another video has also surfaced, which caught Tristan making out, motorboating, and sexually touching two other women at a hookah lounge just outside Washington D.C. in October. Khloe would have been three months pregnant at the time.

"Tristan has been consistently cheating on Khloé. He's a serial cheater. And there will be more women to come out of the woodwork," a source told PEOPLE. "First Lamar cheated on her and now Tristan. She's been through so much," the insider added.

But this isn't the only source who isn't surprised by Tristan's betrayal.

"None of his friends are surprised by this and they all know he cheats," they told Us Magazine. "Most of his friends and people in his circle also cheat and don't think there's anything wrong with it."

While the starlet has yet to release a statement, an insider close to Khloe said she "focused on the positives" of their relationship.

"As far as she knew, there were no negatives," the source said. "Once she made the decision to commit, she was all in and trusting."

"He was her everything. They had a life together. She honestly thought he treated her like gold, like a queen," the source added. "[He] gave her everything, doted on her, told her how beautiful she was. To her, life was perfect. And it all just came crashing down."

But, despite this sad situation, some media outlets are speculating this all has to do with karma.

Karma is a b*tch

Social media users were also quick to point out Tristan's infidelity on Khloe may be a result of karma.

Back in 2016 it was rumored the basketball star cheated on his pregnant girlfriend, Jordan Craig. It was reported Khloe and Tristan first got together in September of that year, just four months before Jordan was due to give birth to their son, Prince Oliver.  

But, neither Khloe or Tristan have ever commented on the claim, and have insisted they were introduced on a blind date, which was arranged by a mutual friend.

Following the breaking news report, Jordan took to social media to denounce the rumors she wished Khloe ill will during this heartbreaking time.

"If you respect yourself and you respect others, you would never make light of the misfortune of anyone, nor would you feel indemnified when it comes at the expense of others," she wrote on Instagram.

Thankfully, Jordan isn't the only one offering Khloe her support, as her family is also rallying around her.

Family rallying around her

After footage of Tristan's adultery was released, Khloe's family has shown their steadfast support to the Keeping Up with the Kardashians star.

"Kris has gathered the family and made sure they would all be there for her," a source told ET. "They are so excited for Khloé. Her sisters are being super supportive of her... her family is rallying around her."

"The video hasn't stopped the Kardashians from making sure her day will be one of love and respect," the insider continued. "They won't let any news change the importance of how beautiful this birth is for Khloe. They want her to focus on having a healthy experience," adding they are shielding her away from all of the media reports.

But, despite the famous family's support, reports are emerging Khloe's mother and sisters were wary of the couple's courtship from the beginning.

"Khloé's mom, Kris, and sisters Kim and Kourtney, all had concerns about her relationship with another basketball player, and now their fears appear to have serious merit," an insider said.

"Women are constantly throwing themselves at professional athletes, and it's very easy to stray when teams are on the road. Kris never expressed her fears to Khloé because she felt it would cause nothing but drama and create tension," they added.

Since the incident was revealed, the entire Kardashian family has unfollowed Tristan on Instagram, including Kourtney's ex-boyfriend, Scott Disick.

What's next?

While Khloe has yet to comment on Tristan's infidelity, her family hopes these allegations are just grossly misconstrued.

"At this point, Khloe's family wants nothing more than to believe that he is a stand-up guy and that this was a setup," the same source told ET. "But only time will tell."

Unfortunately the claims are most likely true, as the other woman added fuel to the fire by posting a series of incriminating pictures on social media.

Even though her Instagram account has since been suspended, she wasn't done wrecking the already tattered relationship. Along with releasing the alleged sex tape between the two, she also posted a text from Tristan himself, which read: "If I was there I would grab u while u try to walk away from me than I would pull ya hair and kiss you than rip ya clothes off and lay u down while I suck ya p**** and say sorry."

To put the final nail on the coffin, while defending herself from an onslaught of criticism, she claimed Khloe wasn't the only one pregnant.

"I'm pregnant too since everything out there," she defiantly wrote. Whether this is true or not, only time will tell.

Do you think Khloe should kick Tristan to the curb?
