Jonas Brothers play the weekend viral anthem with Nick playing the piano and serving as the lead singer, while Selena showcases 'Who Says' with The Scene.

Nick Jonas knows how to delight his fans. During his performance with his Jonas Brothers bandmates at Concert of Hope on Sunday night, March 20, the youngest member of the band sat behind a white grand piano and covered Rebecca Black's viral hit "Friday".

Nick sangs lyrics, "Gotta get down on Friday/ Lookin' forward to the weekend/ Friday, Friday/ Gettin' down on Friday/ Lookin' forward to the weekend/ Partyin', partyin' (Yeah)/ Partyin', partyin' (Yeah)/ Fun, fun, fun, fun/ Lookin' forward to the weekend."

Another musical guest at the annual benefit concert was Selena Gomez. The teen singer showcases her new single "Who Says" live for the very first time with her band The Scene. She looked beautiful in a Mandalay's fuchsia hued crystal plunging neckline dress and Tory Burch "Eddie" flats.

Concert of Hope was held at the Gibson Amphitheatre in Los Angeles, California. Also coming to support the event were Allstar Weekend, all-girl group Cherri Bomb, "Camp Rock" actress Anna Maria Perez de Tagle, Radio Disney host Jake Whetter and YouTube star Christina Grimmie.
