Britney Spears is headed to Las Vegas as a headliner this fall and already looks ready to squeeze into the skimpiest of costumes.
“Britney at her best! 31, firm & fabulous,” reads the cover of Shape magazine featuring a slimmed-down Brit in a tiny white Deja Soleil Swimwear bikini.
“She’s so inspiring to be in that great of shape after having two kids,” says Deja Berkham, designer and owner of the line. “All Deja Soleil suits are designed to play up a woman’s delicate curves and still be durable enough for the most active of women – much like Britney.”
The pop star is expected to start rehearsals in late September or early October for a run of Sin City shows at Planet Hollywood that could begin around November, the Las Vegas Sun reports.
And for those wondering whether Spears got her Shape shape more from Photoshop than diet and the gym, take a look at this picture from a few weeks ago: Spears lounging in Malibu in a barely there bikini.
