VIDEO: WILL SMITH GET'S IT IN FREE STYLES WITH DOUG E. FRESH AT GABRIELLE UNION B'DAY PARTY

Big Will also performed “Summertime” and the theme song from “The Fresh Prince of Bel-Air” as celebrity guests including Dwyane Wade looked on. They didn’t stop there, rhyming over Cali Swag District’s “Teach Me How to Dougie.”

“Wow. Epic night. Fresh prince and dougie fresh just shut it down,” tweeted D-Wade.

Will Smith and Doug E. Fresh were the life of the party while attending Gabrielle Union’s 40th birthday celebration in Miami on Saturday. Wearing a Phillies cap, the Fresh Prince got on the mic and freestyled while Doug E. Fresh beatboxed.

“I’m thinking about taking the H and O out of Hollywood, putting a W-I and make it Willywood/ That’s kinda hot, I really should/ Crazy thing is if I want to, I really could,” rapped Will, who rapped a similar verse on “106 & Park.”
