As their U.S. tour rolled into Philadelphia, One Direction decided to tackle a surprising yet appropriate cover for their fans at Lincoln Financial Field stadium. It only made sense that while in the city Will Smith was born and raised, the quartet would deliver a rendition of The Fresh Prince of Bel Air's unmistakable theme song.

Irish heartthrob Niall Horan manned lead vocals for the group's impromptu version of the classic Smith hit whose second verse proudly proclaims: "In west Philadelphia born and raised / On the playground was where I spent most of my days/ Chillin' out maxin' relaxin' all cool / And all shootin' some b-ball outside of the school."

According to Billboard, the last-minute cover saw wildly positive reactions from the stadiums 70,000 fan capacity while Horan later joked, "We didn't think that through. We needed to rehearse it!" He continued to joke, "I'm going to be president in 2020." The rest of the group, which will break for hiatus in 2016, was in agreement that the song should've ended on a better note. Harry Styles, who can't seem to shy away from falling on stage, shouted "it wasn't clean" before tossing his microphone to the floor and jokingly walking away.

Last month, it was revealed that Smith plans to revive a similar show to NBC's The Fresh Prince of Bel Air which saw its six season run form 1990 to 1996, NME notes. The actor starred in the series as a teenager hailing from West Philadelphia, forced to live with his wealthy family members in the Bel Air community.

Smith would act as producer for the impending series, which is rumored to move the show's action to modern day Los Angeles while drawing inspirations and undertones from the original hit show. The I Am Legend actor's own production company, Overbrook Entertainment, will prepare the pitch for the Fresh Prince inspired series to numerous networks in the US.
