Kate Hudson isn't just looking good these days -- she's looking great. She recently split from fiance Matt Bellamy and she's not wearing any makeup here, so that's really saying something!

Kate's trainer also seemed to be checking out her fab figure, but with a pair of shorts like this, how could you not stare at the starlet's amazing legs and derriere?!

Kate has always had a bubbly personality, so we don't want to assume anything, but you never know...
