Making the most of every free moment!

Katy Perry and some of her backup dancers capitalized on their downtime from her Prismatic tour in Missouri on Monday by hitting the local waterpark for some fun in the sun, and the singer showed off her enviable bikini body in an Instagram video posted for fans!

"Hi from the [fish emoticon] on #theprismaticworldtour," she captioned the vid, which shows the whole group dunking underwater while giving the peace sign. We bet it would a blast to work with the pop princess! The songstress is performing a show at Kansas City's Sprint Center tonight, and will head to Nebraska on Wednesday for another performance.

She is hot and seems super fun, so we think John Mayer made a huge mistake letting her go!
