On Tuesday, Sept. 22, Raven Symone and Anneliese Van der Pol reunited on stage at NYC's 54 Below to perform the "That's So Raven" theme song.

Us Weekly reports that Van der Pol brought out her fellow "That's So Raven" co-star Raven Symone as a surprise guest. Symone sang the popular "That's So Raven" theme song while Van der Pol sang backup.

"I love you, I think you're a genius," Symone told Van der Pol prior to singing her former hit TV show's theme song. Following her performance, Symone added, " "I haven't sang in front of people in a really long time."

In addition to singing the "That's so Raven" theme song, Van der Pol and Symone also performed covers of a wide array of hit songs including Frank Sinatra's "That's Life" following a snazzy rendition of "Happy Birthday" which Symone performed in honor of Van der Pol's birthday, Entertainment Weekly reports.

Last month, Van der Pol and Symone reunited with even more of their fellow "That's so Raven" cast members on "The View," Us Weekly reports.

Symone invited her former "That's So Raven" cast members Orlando Brown, Anneliese van der Pol, and Kyle Massey to join her to discuss their experience working on the hit Disney series.

Van der Pol revealed that the show was originally called "Absolutely Psychic" while Symone revealed that Van der Pol initially did not get the part of Chelsea, her quirky and ditsy best friend on the show.

"Somebody else had the part, it was actually named a different show altogether ... and I remember when we were in the audition room, I told them, 'I'd rather play best friends with her than the girl you guys picked,'" Symone admitted.
