NBA star Tristan Thompson‘s mother, Andrea Thompson, has died of a heart attack.

According to close sources, Tristan’s mom suffered a heart attack at her Toronto home. She was rushed to a local hospital where medical experts tried to resuscitate her, but she didn’t make it.

Tristan flew to Toronto to be with his family, with his ex Khloé Kardashian joining him to comfort and navigate him through the next few days, according to a source. Khloé was close with Andrea, they add.

Tristan and Khloé share two children together, True and a baby boy born in August via surrogacy. He is also dad to 12-month-old son Theo with Maralee Nichols and 6-year-old son Prince with ex Jordan Craig.

Tristan last played in the NBA for the Chicago Bulls during the 2021-22 season. He has remained a free agent since parting ways with the team.

Looking at Tristan’s social media pages, he and his mother seemed very close. Sending condolences to Tristan and his entire family.
