In a recent concert in Connecticut, Jennifer Lopez brought out one of her longtime collaborators, Fat Joe.
Joe joined J. Lo onstage for a rendition of "Feelin' So Good" off of her 1999 debut album On the 6.
The song also features a verse by the late Big Pun, which Joe helped spit.
The duo also collaborated on Lopez's song "Hold You Down." Both took to Twitter after their performances.
