Our source confirmed to us that Miley's assistant signed a waver "Miley Cyrus" and "Nick Jonas" to ride the ski -- just in case someone got hurt! Niley rented their jet ski at Tybee Jet Ski & Water Sports. The cost? $89 an hour for one rider plus $15 for an additional rider.
Remember our source also confirmed to us that Nick and Miley were caught kissing!
