Ahead of the birthday festivities, Thompson shared a heartfelt tribute to the Revenge Body star, uploading a photo of himself and Khloe being all smiles while lying on a trampoline with their daughter.
The former couple was first spotted together in September 2016 after Kardashian had finalised her divorce from ex-husband Lamar Odom.
In late 2017 Kardashian announced her pregnancy and moved to Cleveland to be with Thompson. However, a couple of days before the star gave birth to her daughter on April 12, 2018, evidence of Thompson with another woman at a New York nightclub surfaced, along with surveillance footage of Thompson being close with two mystery women at a shisha lounge in Washington D.C.
Several other cheating allegations were brought forward against the Cleveland Cavaliers player, which Kardashian later confirmed and forgave Thompson- only to be hit with another infidelity scandal almost a year later.
In February 2019, Thompson was reported to be caught kissing Jordyn Woods, who was close to the Kardashian clan and was known to be Kylie Jenner's best friend, at a house party. Thompson and Kardashian then called it quits.
In the year that followed, the pair chose to work through their relationship and remain on friendly terms. By April of this year, Kardashian admitted to be considering having a second baby with Thompson in spite of the separation. An episode of Keeping Up With The Kardashians revealed Thompson as "on board" with being a sperm donor as the reality star freezes her egg.
