Britney's younger sister, Jamie Lynn Spears, surprised the singer onstage by presenting the inaugural award, reported abc News.
Actress-singer Hailee Steinfeld and the show's hosts Kelsea Ballerini and Sofia Carson teamed up to pay musical tribute to the 35-year-old pop diva and performed a medley of her biggest hits, including "Circus" and "Till the World Ends".
Accepting the award from her sister, Britney said, "What a pleasant surprise, my goodness! I want to thank Radio Disney so much for giving me their first-ever Icon award. What can I say? This is such an honour! Your support throughout my career has meant so much to me.
