Earvin Johnson III, known as EJ, is a student at NYU and had not previously made his sexuality public. The news, however, isn't a surprise to his parents.
"Cookie and I love EJ and support him in every way," Magic Johnson told TMZ. "We're very proud of him."
Magic, who spent his storied career with the LA Lakers and now holds a stake in the Dodgers, has not shied away from speaking out on California's fight over gay rights and same-sex marriage.
In 2008, ahead of the vote on Proposition 8, he called for Californians to defeat the measure.
"Prop 8 singles out one group of Californians to be treated differently -- including members of our family, our friends, and our coworkers," he said in a recorded telephone message sent to California voters. "That is not what California is about. So this Tuesday, vote no on Proposition 8. It is unfair and wrong. Thanks."
