Max George's girlfriend is truly a multi-tasker ... she can PDA and pick the thong out of her ass AT THE SAME TIME!!!!
Max -- the guy from The Wanted who once banged Lindsay Lohan -- took his hot model GF Nina Agdal to a beach vacation in the Bahamas ... where they galavanted around with their ridiculously attractive tan bodies.
They spearfished ... they yachted ... they boozed -- and most importantly, they documented almost the entire thing on camera so everyone could follow their half-naked vacay.
