LeBron James doesn't go easy on anybody.
The Cleveland Cavaliers superstar is kicking off his offseason with some good ol' family fun, celebrating his son Bryce's 10th birthday with a sports-themed bash Saturday.
Despite the younger competition, King James didn't seem to hold back in a water-balloon fight as he showed off his impressive throwing arm and ran around like it was an NBA game.
Here are more photos from the party:
Happy birthday, Bryce!
