Once a cheater, always a cheater. Tristan Thompson knows he is in hot water with Khloé Kardashian after multiple videos of him cheating on his baby mama surfaced. So, it is no surprise that he's begging for Khloé's forgiveness just days before the arrival of their baby girl.

"[Tristan]'s been in Khloé's ears apologizing, telling her that these videos aren't what they look like," a source told In Touch exclusively. "He's telling her that the girl he was with at the hotel is [a friend of a friend] and that the video of him kissing that chick last year was a stupid bet he made with one of his teammates."

This is not the first time Tristan has been caught cheating on the KUWTK star. In February, In Touch shared photos of the NBA star getting flirty with a mystery woman — and sources saw the couple leave the event together. "Tristan definitely has a type, and she dressed the part. She wore a white bodycon dress with a back slit. Her hair was dirty blond with a middle part and was styled super straight with a straight-line. The length was about to her shoulders. She looked to be about 25-27 years old," the eyewitness said. "She was rubbing up and down while she was whispering to him. He never fully put his arm around her, however, they were standing really close at times. So close that when he would put his hand down by his side, his hands would lightly graze her backside."

Last weekend, Tristan, 27, was spotted hooking up with another woman in NYC, who reportedly shared a sex tape and dirty text messages of the couple. And let's not forget about Tristan's decision to seemingly leave his first baby mama Jordan Craig while she was pregnant with his son, Prince, to be with Khloé.

It's no surprise that the Internet has dubbed the athlete "third trimester Tristan" and hinted that Khloé was partially to blame for the infidelity. "No encouragement bihhh she took someone's boyfriend. Karma is a serious thing," one hater wrote before another added, "You lose them how you get em." Some even hinted she should name her daughter Karma. Ouch.

However, Jordan disagrees, and shared a sweet message seemingly directed at Khloé amid the scandal. "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. Wishing peace for everyone," she wrote. We couldn't agree more.
