Britney Spears In Sexy Bikini At Beach: Poking through a thin tank top? Heck, Britney Spears can do that, and does, in her sleep. But through a padded bikini top? Far more impressive, Brit. Certainly, Britney Spears has lost a step or two (and gained a pound or two) in her game, but there's no denying what these Britney Spears bikini pictures prove: her nipples remain as pert and powerful as ever.
