Will Smith learned a lot from Uncle Phil, on and off screen.

The actor is speaking out about his "Fresh Prince of Bel-Air" costar James Avery's death, memorializing him in a new Facebook post and sharing the last photo of the cast together. 

"Some of my greatest lessons in Acting, Living and being a respectable human being came through James Avery," he writes.

"Every young man needs an Uncle Phil. Rest in Peace," Smith adds in his statement.

Will also posted a shot of him, James, Alfonso Ribeiro, Karyn Parsons and Tatyana Ali, which was taken when they reunited at a charity event back in 2011. 

"This photo was the last time we were together," Smith wrote in the caption.
