The clubs won't be spinning Britney Spears' new single this weekend.
According to label sources, the official premiere of "Womanizer," Spears' first single off of her upcoming album Circus, has been pushed back due to an undisclosed issue with "the mix"—i.e. not Britney's vocals, per se, but rather how all facets of the track sound together.
Originally set to drop this morning, the masterminds at Jive Records' Zomba Label Group are holding the song for at least another week, meaning radio stations won't be spinning the tune until Sept. 29 at the earliest.
"The mix was not finalized," a source told E! News.
