Jamie Lynn Spears surprised her big sister, Britney Spears, at the 2017 Radio Disney Music Awards on Saturday, April 29, when she appeared on stage to present the pop superstar with the first-ever Icon Award.
Clad in Britney-inspired ensembles, the show's hosts, Kelsea Ballerini and Sofia Carson, were joined by singer-actress Hailee Steinfeld to perform a medley of Britney's biggest hits, including "...Baby One More Time" and "Circus." Toward the end of the performance, Jamie Lynn, 26, joined the trio on stage to sing "Till the World Ends" before handing the inaugural award to her sister.
"What a pleasant surprise, my goodness!" Britney, 35, exclaimed as the audience cheered her name.
Earlier in the night, Preston and Jayden had the chance to meet one of their favorite singers, Nick Jonas.
"My boys and @nickjonas woo hoo #RDMA," Britney captioned a cute picture of her sons with the "Close" crooner, 24.
