Will Smith Freestyles at Gabrielle Union’s Birthday Party

When Doug E. Fresh dropped the beat box, actor Will Smith, aka “The Fresh Prince,” responded with some verses off the top at actress Gabrielle Union’s birthday party in Miami Saturday Night.

Smith took the stage in a Phillies baseball cap and spit a freestyle that went a little something like this:

Yo the champ’s in town/You can’t sit down

Yo, I’m slow to sit, infecting victims with the vapors/ No time, I’m chasin’ paper…..

When I walk to the stage like a big fight /All cheers, no jeers/ I been kickin’ for years, right…

And then the DJ dropped  the 1991 hit “Summertime” from Smith and DJ Jazzy Jeff’s fourth album “Homebase,” along with some other crowd pleasers.

Gabrielle Union, who turns 40 on Monday, came to the stage and hugged both Fresh and Smith for their tribute.
