Watch Jamie Lynn Spears Surprise Britney During Her Radio Disney Icon Award Tribute

Britney Spears was met with a mega-surprise during her Icon Awards presentation on Saturday night (April 29) at the 2017 Radio Disney Music Awards when her sister Jamie Lynn showed up and performed alongside Hailee Steinfeld, Kelsea Ballerini, and Sofia Carson.

Ballerini kicked off the five-minute tribute performance with a guitar-charged performance of "Oops! ... I Did It Again," before Steinfeld offered up "Circus" and Carson delivered a spot-on rendition of "... Baby One More Time." It was a pleasant delivery, but things kicked up a notch when Jamie Lynn appeared on-stage and surprised her big sister with an outro performance of "Till the World Ends." 

With her two sons and mother by her side, Britney left her seat and took to the podium to accept Disney's first-ever Icon Award and was met with a roar of applause and chants. "What a pleasant surprise, my goodness," the pop titan told the crowd. "This is such an honor. I want to thank Radio Disney so much for giving me their first-ever Icon Award. Your support throughout my career has meant so much to me, all of my fans, as always, you are the freakin’ best."

Spears went on to thank the "two loves of [her] life." "My sons Jaden and Preston, you're the reason my heart beats. I love you so much," she continued on.
