Surf's Up !!!
Jake Paul's fiancée Jutta Leerdam made a splash in more ways than one at an indoor water park on Friday -- turnin' heads with her surfin' skills ... and teeny bikini!
The couple seemingly took a break from filming their new reality show, "Paul American" (we see no TV cameras in sight) ... and hit up the DreamWorks Water Park in East Rutherford, NJ to catch some waves at Skudin Surf.
Leerdam -- an Olympic speed skater -- went solo, proudly filming his boo as she rode the waves, showcasing her incredible athleticism, and drop-dead gorgeous body!
