Kailyn, her boyfriend Javi, and a few of their besties are currently on a mini-vacation in Ocean City, Maryland, and Kailyn isn't shy of showing off her toned bod. We're loving Kail's itsy bitsy, teeny weeny, yellow polka dot bikini!
This gal shed the pounds thanks to a healthy diet and an exercise regime called Insanity (hardcore!), but she thinks beauty comes in all shapes and sizes, and even lent her celeb image to the Beauty Is Sizeless campaign. Check out her sexy photo here!
Kailyn looks amazing all the time, but we have to admit … all that hard work has definitely paid off!
Is Kailyn's beach bod hot or not?
