American reality star and socialite, Khloe Kardashian, has reportedly split from her partner and baby father, Tristan Thompson, over an alleged affair with Kylie Jenner’s best friend.

The mother of one ended her two-and-a-half-year relationship with the Cleveland Cavaliers player immediately she discovered he was cheating with Jordyn Woods.

Tristan flew to Los Angeles to spend Valentine’s Day with Khloe and their daughter, True, but on Sunday night, he was at a house party and was allegedly spotted making out with Jordyn, TMZ reports.

Tristan, reacting to the news wrote on Twitter, “Fake News,” but deleted the tweet soon after.

Khloe however, disagrees with Tristan by commenting with shouting emojis on a Hollywood Unlocked Instagram post about the cheating.

Multiple reports say the entire Kardashian family is devastated by Jordyn’s betrayal.

The 21-year-old model was closest to Kylie but formed part of the entire family’s lives, including as a model for Khloé’s clothing line, Good American.

Kim, Kourtney, Khloe, Kendall and Kylie gained popularity thanks to their Keeping Up with the Kardashians reality show.
