Tristan Thompson’s mother has passed away.

According to reports, the NBA star’s mother, Andrea, died unexpectedly in Toronto on Thursday, January 5th.

She suffered a heart attack in her home this week.

She was rushed to a local hospital where medical responders worked to resuscitate her.

Sadly, their valiant efforts weren’t enough to save her life.

TT left Los Angeles as soon as he got the news, so that he could be with his family in Canada.

Andrea has been very involved in her two sons’ lives.

She has a younger son, Amari Thompson, who suffers from epilepsy.
