The Fresh Prince of Bel Air cast just filmed a reunion and it's out today!

"Now this is a story all about how my life got flipped turned upside down..."

The Fresh Prince of Bel-Air Reunion is coming tonight, after Will Smith revealed a trailer showing the Banks family back together 30 long years after the hit sitcom's debut.

In the trailer, the Banks family - including Tatyana Ali, Karyn Parsons, Joseph Marcell, Daphne Maxwell Reid and Alfonso Ribeiro - as well as recurring co-star DJ Jazzy Jeff - return to the Banks home for a look back at the show and to reminisce about old times, how much the show blew up … and how amazing their chemistry was.

In an emotional move, Smith sat down with Janet Hubert, who was the original of Aunt Viv, for the first time in 27 years.

Check out the trailer below:

The Fresh Prince of Bel-Air originally aired from September 1990 until May 1996 and was the show that launched Will Smith's career.
