Thompson concluded by thanking fellow NBA player, Brandon Jennings, "for bringing this King and Queen together."

The two were first linked publicly last year.

Kardashian opened up about her relationship with the NBA player earlier this year. She told Evening Standard magazine in April 2017 that she's "never been in this type of love" and would "love to have a family" with Thompson.

"He [already] is a father, and I know for a fact that he would be an impeccable father," she said, referring to Thompson's son with ex Jordan Craig, who just turned 1.

"I definitely want to be a mom. But I don’t put the pressure on it. It’s not like, 'The clock is ticking,'" she continued. "I feel in my soul it will happen."
