In between performances of her California Dreams tour, the pop singer spent a few days visiting her husband Russell Brand, who is Miami filming Rock of Ages with Tom Cruise and Julianne Hough.

Katy showed off her covetable curves in the lingerie-style swimsuit, with her newly lightened and reddened locks wrapped up in a bun on her head.
