Knowing how much Ellen loves jokes and pranks, Zac Efron and Taylor Swift took the opportunity to perform a number of “dance dares” for a video to show the host on The Ellen Show.
Among the “victims” of the dance dares were Selena Gomez, her boyfriend Justin Bieber, and the loveable firecracker Betty White.
The trick is to dance behind people without them knowing.
Swift and Gomez has been friends for awhile and Gomez even helped her country star friend end last year’s 17-country tour, coming on stage to sing her hit “Who Says” with bff Swift.
Watch the hilarious video below.
