Affair and split rumors have, once again, hit Khloe Kardashian. With the allegations that she and Tristan Thompson are facing these days, the holidays are said to be "looking grim" for the reality star.

Sources told Us Weekly that this is a "sad time" for Kardashian as she thought Thompson might have already changed his ways. But, amid all the controversies, she, reportedly, knows that the father of her child was "unfaithful to her, again."

Even so, insiders noted that the "KUWTK" star is trying to put on a brave face for her daughter. She is reportedly "staying strong," alongside her family who has remained supportive of her amid all the drama.

On December 2, a reported former friend of Tristan Thompson gave birth to a child. It is alleged that the NBA star is the father, with claims that their relationship began "at least five months" before Thompson's 30th birthday in March, and continued throughout the pregnancy.

Reports continued that she is said to have requested child support, payment for medical expenses, newborn costs, and a birthing doula. This explains the paternity court documents, which publications have obtained, with the professional basketball player reportedly asking for a paternity test.

The paternity lawsuit is still ongoing. However, the details have been sealed as the online filing is no longer searchable, according to Page Six.

As stated, the records are now listed as "confidential or this case has been sealed." It is, then, added that Tristan Thompson reportedly filed an order to stop the alleged former friend from speaking to the media regarding the case.

Amid all the controversies, though, Khloe Kardashian has remained silent about the matter. The same goes for the father of her daughter, who has not confirmed nor denied the allegations.

Meanwhile, the Good American co-founder seemingly continues to share updates on social media. On Sunday, she posted a "sweet" photo on Instagram, featuring her and her 3-year-old daughter.

People said they had just attended a "Sing 2" screening party at Kim Kardashian's house. Clips and snaps from the event, also, emerged from the reality star's Stories on the same platform.

The following day, witnesses spotted Khloe Kardashian with best friend Malika Haqq and her son as they headed toward her daughter's dance class, according to The Daily Mail.

As seen in the photos, she dressed down for the outing, wearing a black sweatshirt and sweatpants. The same, also, goes for Haqq who was in a black ensemble.
