Nina Agdal's breaking necks while on vacay ... she gets ya coming and most definitely gets ya going.
The supermodel was spotted -- quite literally -- wearing the hell outta this leopard bikini while in Capri with her boyfriend -- Christie Brinkley's son -- Jack Brinkley-Cook. She soaked in some rays but had plenty of time for some PDA with Jack. #Jelly.
They also took a dip and did so in style, jumping off a cliff. And, from the look of things, Nina stuck the landing!! Capri's the place to be ... if you're rich and pretty, anyway.
