As more details unfold regarding Tristan Thompson being caught cheating on Khloe Kardashian, sources are now revealing how this new shocking story is effecting Khloe's family.

The Kardashian-Jenner family has been known to be very protective of each other, particularly when one of the siblings is expecting a child, so it's no surprise that this newest revelation isn't sitting too well with Khloe's siblings.

The Kardashians Aren't Having It

Khloe's family was reportedly "concerned" about Thompson being involved in her life. Khloe had already dealt with a difficult situation with her ex-husband, Lamar Odom, who was battling a severe drug addiction while the two were married, and Khloe's family didn't think Thompson would be any better for her.

"When Khloé first started dating Tristan, her family questioned if it was a good idea. There were several concerns, including that he is another basketball player and also that his ex was pregnant. It took a while for the family to accept Tristan. They were worried that Khloé would end up heartbroken," a source stated to People magazine.

Thompson's ex-girlfriend, Jordan Craig, was pregnant with his son, Prince, when he began his relationship with Khloe. While there hasn't been any confirmation if Khloe came between Thompson and Craig, Craig apparently wasn't too happy about the couple's relationship. It was also mentioned that in the beginning, Khloe's mother, Kris Jenner wasn't too fond of Thompson but did eventually warm up to him.

Khloe's Health Is The Main Priority 

Khloe's due date is drawing closer and closer, and as of now, her family is reportedly making sure she and her baby are okay. 

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

It has also been reported that Khloe's family is "hoping" that the video is a set-up and that the athlete will still "do right" by Khloe, but only time will tell how everything will unfold.

The video of Thompson allegedly cheating on Khloe surfaced on Tuesday, April 10. Thompson appeared to be kissing another woman at a nightclub in New York City. Sources also claim that Thompson and the mysterious woman also left the club together. 

Khloe is pregnant with her first child, a baby girl, who is due this month. The Keeping Up with The Kardashians star has always wanted children and a family of her own. In the past, Khloe opened up about her fertility issues and at one point considered having her first child via surrogacy.
