Britney Spears is channeling Katy Perry's "California Gurls": daisy dukes, bikini on top!

The singer, 28, continued to show off her body -- taut and better than ever -- hanging out with her man Jason Trawick in Maui, Hawaii on Thursday. Check out more hot shots of Brit on the beach!

Although things are going well with former manager Trawick -- they've been dating for over a year -- Spears recently used her Twitter to slam a tabloid report that they're planning to get hitched in a "double wedding" with Spears' little sister Jamie-Lynn.

Spears recently confirmed she's back in the recording studio making the follow-up to her 2008 smash Circus; she also recently filmed her talked-about appearance on Glee.

"Britney was very professional and very much the sweet Southern belle," a set source says in the new Us Weekly. "Her attitude was, 'I'm here to work, let's do this!'"
