Only the best for Britney Spears, who is rocking one pricey sports bra in new promo photos for Twister Dance.

The sexy pop star shared some pics from the set of her new commercial this week, where she's shows off her tight tummy in a sports bra worth over $20,000!

While it doesn't look like much in the photo, the bra is actually adorned with 18K gold skulls with diamond eyes. It's also made with French silver threaded fabric and covered in Swarovski crystals.

The "Eternal Love" bra from BodyRock Sport by Kelly Dooley has a retail price of $20,011 and is available online ... if you've got the spare change.
