"Happy birthday @khloekardashian," the 30-year-old NBA star wrote on Instagram late Sunday morning. "Thank you for being not just an amazing partner, mommy and best friend but also being the kindest, caring and most loving human being I've ever met. Your love and spirit is contagious to all who've met you."
Along with two red heart emojis, he added, "Thank you for always being there for me and putting our family first. I love you so much. Have an amazing day."
The photos that accompanied the heartfelt caption showed Tristan kissing the Keeping Up with the Kardashians alum's head, them two hugged up on a couch together and a car selfie featuring their 3-year-old daughter, True Thompson.
What makes this birthday shoutout particularly interesting is that Kardashian did not acknowledge Thompson this past Father's Day, as the two are said to be on bad terms.
As Radar previously reported, the Boston Celtics power forward/center was accused of cheating on the Good American founder after he was caught sneaking into a bedroom with three women at a house party in Los Angeles earlier this month.
Sources said Tristan reappeared 30 minutes later, looking "disheveled," while another partygoer claimed he was also seen grabbing a girl's butt during the event.
While KUWTK fans felt sympathy for Khloé, Page Six reported the duo had actually broken up weeks prior to the alleged incident.
It's a convenient narrative considering the two looked pretty cozy at lunch together with True, just days before you-know-what hit the fan.
Though she has not spoken about the breakup or scandal publicly, Khloé did post a cryptic message to her Instagram after her baby daddy's alleged escapades made headlines.
Channeling one of her favorite writers, Kardashian told her 159 million followers that she was "at peace" with her life.
However, that doesn't mean it's over for the duo, as Radar learned that she would "forgive him in a second."
According to our sources, "Khloé just can't quit Tristan. Some of it is that they share a 3-year-old daughter together, but most of it is that she loves him."
Despite being served with legal papers, Kimberly has not showed up to any court hearings, so Tristan's legal team asked the court to award them a default judgment in the amount of $102,000.
Thompson claimed Alexander's public accusations had cost him a ton of endorsement deals and ruined his reputation, but he failed to mention that he's been accused of cheating on Kardashian numerous times in the past.
The judge presiding over the case has yet to officially grant a default judgment but said he was leaning toward it; however, since Tristan failed to prove he had lost any endorsement deals because of Kimberly's claims, he'll likely walk away with $50,000.
Only problem is, she says she doesn't have the money.
