LeBron James is one of the greatest basketball players of all time, but he's also a dad and a child at heart.

The Cleveland Cavaliers icon shared a heartfelt post on Father's Day, saying he's proud to be the dad of Bryce, who celebrated his 10th birthday on Saturday.

James, who has two other children as well, participated in all the fun activities, including football, hoops, and a water-balloon fight.

"LeDad" appeared to dominate in the pickup basketball game, as the 6-foot-8 forward towered over the youngins and threw down some powerful slams.

James also posted a photo from the sports-themed bash.
