Will Smith Performs “Summertime” And “The Fresh Prince Theme Song” At Gabrielle Union’s 40th Birthday

Saturday night, DWade’s boo-thang Gabrielle Union turned the big 4-0. To celebrate, she threw a huge party in Miami that brought out her A-List homies, including “The Fresh Prince” Will Smith. Big Willie From Philly didn’t buy Gabby a present, but he did give her a gift, a rare performance of his old school hit “Summertime” as well as a brief rendition of the theme song that he made famous in the early 90′s.

Peep the video shot by our friend Julia Beverly at Ozone Magazine.

Does Will still have it??
