Jamie Lynn Spears paid tribute to her older sister Britney at the Radio Disney Music Awards on Saturday (29.04.17).
The former 'Zoey 101' actress made a surprise appearance at the Microsoft Theatre in Los Angeles to present the 'Toxic' hitmaker with the first-ever Icon Award, and the 35-year-old singer was also honoured with a musical segment featuring a number of her greatest hits by Hailee Steinfeld and two of the ceremony's hosts, Kelsea Ballerini and Sofia Carson.
The trio donned some of Britney's iconic costumes as they belted out 'Oops... I Did It Again', 'Til The World Ends', '...Baby One More TIme' and 'Circus'.
The 'Gimme More' singer began her career 23 years ago on the 'All New Mickey Mouse Club' and was given the Icon Award as she is "a distinguished artist whose career transcends popular culture and whose music is loved by generations of Radio Disney fans."
Britney took her two sons, Sean Preston, 11, and 10-year-old Jayden - who she has from her marriage to Kevin Federline - with her to the ceremony and they were delighted to meet Hero Award winner Nick Jonas.
The blonde beauty shared a picture on Twitter of her boys with the hunky star and captioned the image: "My boys and @nickjonas woo hoo #RDMA (sic)"
Other winners at the ceremony - which was also hosted by Jordan Fisher, Jenna Ortega and Alex Aiono - included Ariana Grande and Niall Horan as Best Female Artist and Best Male Artist respectively, and Fifth Harmony, who were named Best Group, while their fans were also named Fiercest Fans.
As well as presenting and taking part in the Britney tribute, Kelsea picked up two awards, Radio Disney Country Favourite Artist and Radio Disney Country Favourite Song for 'Peter Pan'.
The ceremony will be broadcast on the Disney Channel on Sunday (30.04.17) evening.
