Britney Spears‘ new video for “Circus” has hit the Web!

The clip shows the sexy singer – who celebrated her 27th birthday in NYC Tuesday – dancing in nude-colored sparkles at…the circus!

(Spears famously donned a similar outfit at the MTV VMAs in 2000 – when she sang “Oops!…I Did It Again” and danced a striptease.)

Spears has been traveling the world promoting her new album – also named Circus. Over Thanksgiving weekend, she hit the stage in England, Germany and France.

On Tuesday, she sang “Womanizer” and “Circus” on Good Morning America before hitting up NYC club Tenjune for a – you guessed it! – circus-themed birthday bash.

Spears’ world tour kicks off March 3 in New Orleans.
