Britney Spears  sweats boyfriend happy David Lucado

Another day, another outing for Brit and her new beau!

A day after Britney hit the links with new boyfriend David Lucato, she shopped for interior decor with her man ... hmmm, time to nest?

If her new boy is giving input on home design, could he also be preparing to move in?

Since Brit broke up with fiance Jason Trawick, she's been smiley and happy and is getting out of the house more. Trawick negotiated her X Factor deal and, supposedly, booked a residency for her at a Vegas resort, though that gig has yet to be confirmed.

Maybe Queen B's doing things her OWN way now? By the look on her face, we think she's back in charge of her life and happy about it!
