Britney Spears seems to be permanently in a bikini these days - and this weekend was no exception.

The singer showed off her newly dance-toned physique in a lilac two-piece as she lounged poolside in Miami during a break from her Circus tour.

Britney was joined in the sun by sons Sean Preston and Jayden James, her mother Lynne, and sister Jamie Lynn, who was with her own young daughter Maddie.

The group looked every inch the doting family as they frolicked in the pool, and Lynne snapped some pictures for the family album.
