Cowabungaaaaaaaaa! Alec Baldwin and his model daughter, Ireland, are jumping for joy while vacationing with the 17-year-old beauty's boyfriend in the Hamptons.

On Thursday, Kim Basinger's lookalike daughter posted some fun-filled bikini pics on Instagram of herself, boyfriend Slater Trout and her Emmy-winning dad, jumping off a boat with the caption, "My boys." Looks like her boys are quickly becoming thick as thieves this summer!

Ireland, wearing a baby blue fringe bandeau bikini top and red bikini bottoms, also posted a pic with her pregnant stepmother, Hilaria, relaxing on the boat. Not a bad way to spend the summer if you ask us!

Having beauty, money, fame and a boat sure looks like pretty sweet deal.
