Khloe Kardashian has thrown in the towel, breaking up with Tristan Thompson after she found out her baby daddy allegedly cheated on her with Kylie Jenner's best friend … TMZ has learned.
We're told Tristan flew into Los Angeles to spend Valentine's Day Thursday with Khloe and their daughter, True. On Sunday night he was at a house party, where we're told he snuggled up with Kylie's BFF, Jordyn Woods.
Witnesses tell us Tristan and Jordyn were all over each other … making out. We're told Khloe found out and immediately broke things off with the NBA player … a source tells us "she has had enough."
We're told there's little chance for reconciliation … Khloe and Tristan are done.
