Khloe Kardashian dumps Tristan Thompson after he allegedly cheats with Kylie Jenner's best friend Jordyn Woods

Khloe Kardashian is reportedly done with Tristan Thompson after one of the most shocking cheating claims her family has ever been hit with.

TMZ reported on Tuesday afternoon that the "Keeping Up With the Kardashians" star dumped the father of her daughter, True Thompson, after he allegedly cheated on her with younger sister Kylie Jenner's best friend, Jordyn Woods.

The bombshell allegation claims that Tristan, 27, and Khloe, 34, spent Valentine's Day together with their daughter last Thursday after the NBA star flew in from Cleveland. Three days later, on Sunday night, Tristan was spotted cuddling up to Jordyn, 21, at a house party.

Not only that, but they were allegedly also seen making out at the club, too.

Khloe reportedly found out about his latest bout of cheating two days after that on Monday, which is when she pulled the plug on their relationship -- this time for good.

The outlet reported that "there's little chance for reconciliation" and that "Khloe and Tristan are done." Us Weekly claims to have confirmed the split, with a source telling the outlet that "they aren't speaking."

It's unclear where Jordyn and Kylie would stand if the report is indeed true. The two have been best friends for years, having grown up together. Jordyn was recently on vacation with Kylie and her daughter, Stormi, where they shared a slew of photos together on Instagram.

Us Weekly also reported that the family was shocked by Jordyn's alleged tryst with Tristan.

"Khloe loved Jordyn before this," a source said. "This is completely shocking to Khloe's family."

After the TMZ report was published, Tristan tweeted "FAKE NEWS" before deleting it minutes later.

Khloe and Kardashian pals Malika Haqq and Larsa Pippen seemingly confirmed the report after they commented on an Instagram post standing by the story. Malika commented "STRAIGHT FACTS," while Khloe commented with a bunch of speaking emojis.

Tristan was famously caught cheating on Khloe just days before she gave birth to their first child together last spring. Controversially, she ended up staying with him for the sake of their daughter, True, though she opted to stay in Los Angeles this past fall when Tristen flew back to live in Cleveland during the start of the NBA season.

Khloe and Tristan were last seen in public together getting dinner at Craig's in West Hollywood in January.

More to come.
