Among the weddings guests were Neyo, Beyoncé and Jay Z. Gabrielle Union mentioned on Instagram that she and her boyfriend, James' teammate Dwyane Wade, were attending a wedding, though she wasn't specific about the lucky couple.
James and Brinson have two sons together -- 8-year-old LeBron James, Jr., and 6-year-old Bryce Maximus James.
The 28-year-old Miami Heat star proposed to Brinson at a New Year's Eve party in 2012.
He later told Oprah that proposing to the mother of his children was nerve-wracking. He had Wade hold the $300,000 engagement ring so Brinson couldn't feel it in his pocket.
“I asked him for it right after the ball dropped,” James said. “He was like, ‘You ready?’ I was like, ‘If you don’t give me this ring right now, I ain’t gonna do it.’”
