Britney Spears Leaks Her New Song

Britney Spears inadvertently left her radio blaring one of her new singles, according to X17 who also captured it all on tape, video below.

Brit stopped at a drug store to buy some vitamins on Friday and the mob of photographers (including a few too many from Team X17!) documented her every move. But X17 just might have the scoop! Listen to the music playing in Brit’s convertible as she pulls out — it sounds like our girl!

UPDATE! - Our source confirms it’s Brit’s very own music!

Doesn’t sound like comeback music to me.
