Miles Teller My GF Really Floats My Boat

4/18/2017 7:04 AM PDT

Miles Teller and longtime GF, Keleigh Sperry, didn't have to worry about sinking or swimming as they hit the surf in Hawaii like a normal couple enjoying a romantic vacation.

The two coasted on a pair of floaties Monday in the blue Pacific ... not that they needed them because the water looked pretty shallow. Only thing missing -- a cold one in their hands.

Then again, doesn't look like Miles had an extra hand ... he made sure to keep both on Keleigh.
