Celebrity Sightings In London - May 23, 2013

When "Fresh Prince of Bel-Air" premiered in 1990, the sitcom was an instant success. Star Will Smith, already a popular rapper, catapulted into stardom, and fellow cast members like Alfonso Ribeiro and Tatyana Ali became household names. After the comedy ended in 1996, they all went their separate ways — though they still keep in touch.

Smith and his former music partner, DJ Jazzy Jeff, recently reunited with Ribeiro to see Smith's eldest son Trey deejay in London. Later, Smith and Jeff performed the famous "Fresh Prince" theme song on "The Graham Norton Show," with Ribeiro popping in to do the beloved "Carlton dance."
