Britney Spears finished up a workout on Thursday and her sports bra as well as tank top were unable to keep her nipples from poking through.

Maybe it was really cold in the gym?

Sorry, it was hard not to notice!

Otherwise, it was just a usual visit to the gym for the incredibly disciplined pop star who always seems to be just working out or finishing a dance rehearsal.

We’re not the only ones who admire Britney’s commitment to her fitness regimen as country crooner Miranda Lambert recently opened up to Women’s Health magazine about looking to Brit for fitness inspiration.
