Listen to Britney Spears on iHeartRadio

Britney Spears is sharing some sexy photos from what appears to be the set of her new music video. 

In pictures posted on Instagram over the weekend, the pop star makes reference to the "WorkBitch" set, leaving fans wondering if that may also be the title of her new song. 

Online, Britney has been teasing fans for weeks now with her "All Eyes On Me"  countdown clock that's set to run out on September 17th.  That's also the same day she's scheduled to make an appearance on ABC's "Good Morning America" to make a big announcement. 

The new Instagram photos build on earlier speculation about a possible release date for Britney's new album.  But fans are also waiting to hear more about the longheld rumors about a possible Las Vegas residency.
