Blue Crush babe Kate Bosworth left beau Alexander Skarsgard at home when she went vacationing in Mexico earlier this week, causing ripples of talk on the internet. Those ripples turned into a full-blown tidal wave of speculation about their breakup when Kate was spotted sunbathing and splashing in the surf topless.

Newly single or not, these are some of the best topless shots we've ever seen from the slender blonde. Kate's only onscreen boobage (so far) is a hint of side nip in The Rules of Attraction, and here she is just letting those puppies play freely in the tropical sun. It's a boobtiful thing.
