LeBron James has become a partner in the Fenway Sports Group, which makes the NBA celebrity a part proprietor of the Boston Red Sox, a resource has confirmed to ESPN.

The Boston Globe first reported Tuesday that James and Maverick Carter — his longtime friend and business partner — are currently partners at Fenway Sports Group (FSG).

James and Carter possess an undisclosed amount of ownership stocks of FSG, according to the world. The Los Angeles Lakers star and four-time NBA MVP also will eventually become a partial owner of additional FSG subsidiaries, including NASCAR team Roush Fenway Racing, sports cable system NESN and Fenway Sports Management.

James and Carter would be the first Black spouses in FSG history, according to the World.

The newspaper also reported Tuesday that FSG declared a $750 million private investment from RedBird Capital Partners, which could create the New York-based firm the company’s third-largest partner at an 11% ownership stake.

The RedBird Capital investment is contingent on Major League Baseball’s approval, according to the Globe.

James, 36, formerly held a 2% ownership stake in British soccer club Liverpool, the defending EPL winner, which also falls under FSG possession.

James has claimed to be a fan of Boston’s historic rival, the New York Yankees, and also publicly rooted for its Los Angeles Dodgers in last season’s World Series. The Dodgers lost to the Red Sox in the 2018 Fall Classic and also acquired celebrity outfielder Mookie Betts from Boston in a blockbuster trade last year.
