The boys stood at attention the moment the song began before jumping around, doing cartwheels and shaking their arms to the beat.
However, the video — which appeared on the site on Thursday morning — has since been removed.
As previously reported by AccessHollywood.com, the boys were set to join Britney on her full "The Circus Starring Britney Spears" tour.
"Britney's family is a huge inspiration and she loves having them on the road with her," a Britney rep wrote on her official site in March.
It is unknown if they have joined her on the European leg of the tour, which kicked off on Wednesday night with a show at London's O2 Arena.
