The Banks family is back together!

Alfonso Ribeiro's "Fresh Prince of Bel-Air" costars reunited to watch him show off his skills on "Dancing With the Stars" on Monday.

Karyn Parsons (Hilary Banks) took to Twitter to share a sweet snapshot from the audience, posing with Tatyana Ali (Ashley Banks) and Joseph Marcell, who played the family's British butler, Geoffrey.

"Supporting baby bro, @Alfonso_Ribeiro on @DancingABC w/ @TatyanaAli and Joe Marcell! #DWTS," she captioned the cute candid.

Tatyana was in attendance for another "DWTS" taping, when Alfonso busted out his signature "Carlton" moves.

The 43-year-old actor famously starred as Carlton Banks on the hit sitcom from 1990-1996 alongside Will Smith.

"Carlton was someone I had a blast playing for six years," he said. "I love the Carlton dance. I love how it makes people feel. I certainly don’t do it a lot. But I love the fact that people have this nostalgic look at that dance."

Check out the clip above to see him break into the Carlton -- complete with flailing arms, snapping fingers and swinging hips!

Seeing these former costars together makes us long for a reunion. In fact, Charity Buzz is offering up lunch with Will Smith and the rest of the cast ... but it will cost you!
