The NBA veteran seems to be in good spirits following a public breakup with his girlfriend, musician Megan Thee Stallion.
Klay Thompson didn't enjoy the best season of his career in his second year with the Dallas Mavericks in 2025-26, and soon after the regular season ended, things appeared to get worse.
Rapper Megan Thee Stallion posted a message on Instagram that alleges that her boyfriend Thompson had cheated, all but ending their relationship with a public callout.
Below is what the April 25 message read:
"Cheating, had me around your whole family playing house... Holding you down through all your HORRIBLE mood swings and treatment towards me during your basketball season now you don't know if you can be 'monogamous'????"
In a separate statement to TMZ, Stallion confirmed that the relationship had ended after trust was "compromised."
"I’ve made the decision to end my relationship with Klay," said Stallion in the statement. "Trust, fidelity and respect are non-negotiable for me in a relationship, and when those values are compromised, there’s no real path forward. I’m taking this time to prioritize myself and move ahead with peace and clarity.”
Meanwhile, Thompson broke his silence on social media by resorting to one of his favorite offseason destinations: the water.
Thompson - or "Captain Klay" as he referred to for his love of boating - appeared to go on Instagram Live while riding through the waves.
While he did not address the breakup or infidelity rumors, Thompson appeared to be in good spirits as he made his first public appearance or post since the relationship drama with Stallion, 31, unfolded.
"Good to be back on the high seas!" Thompson yelled in a clip of the live stream.
This story comes at a relatively odd time, considering other prominent Dallas athletes have also recently gone through relationship troubles.
Dallas Cowboys quarterback Dak Prescott called off his wedding in Italy earlier this spring after a reported conflict over monogamy with fiancée Sarah Jane Ramos during the couple's joint bachelor/bachelorette party. Former Mavericks star Luka Doncic was in the midst of a custody battle and breakup with his fiancée earlier this NBA season after he had not reportedly seen his two daughters for months, since the youngest was born in his home country of Slovenia.
Thompson, 36, took on a peculiar role with the Mavs this season, compared to the earlier parts of his future Hall of Fame career.
The sharpshooting veteran started just eight of the 68 games played this season. He averaged a career-low 21.7 minutes per game and shot 38.3 percent from 3-point range. Thompson sits fourth in NBA history with 2,899 made 3-pointers and trails his former "Splash Bro" teammate Stephen Curry of the Golden State Warriors, who is in first with 4,248.
Thompson is entering the final year of his contract, a three-year $50 million deal with the Warriors that was sent over to the Mavericks in a sign-and-trade two years ago.
"I’m not sure," said Thompson when asked if he would be back in Dallas next season.
"I mean, I am under contract, so I do, but I’ve definitely learned in my time in Dallas that things can change on a dime. So just here to have great timing, put my best foot forward, and that’s all you can do."
