Wilde, 31, showed off her impressive physique in not one, but two, bathing suits: a sporty paisley two-piece (above) and a bright red string bikini (below).
And it turns out that mom isn't the only one in the family who likes to show some skin. Wilde posted an adorable Instagram photo of little Otis taking in the Hawaiian landscape wearing nothing but a cowboy hat.
"Naked cowboy," the Vinyl star captioned the cute photo that will no doubt embarrass him one day. Until then, we just love it!
