Britney Spears New Music 2013 RUMORS: 'Good Morning America' Sept. 17 Countdown? 'Ooh La La' Singer to Perform New Single, Announce Las Vegas Residency?

It seems that Britney Spears' mysterious "All Eyes On Me" countdown will end with a talk show appearance. The countdown clock on the "Ooh La La" singer's official website will hit zero at 9:30 a.m. on Sept. 17, and that is when Spears is reportedly going to appear on "Good Morning America."

According to Digital Spy, Spears will show up at "GMA" to mke a "top secret announcement." Though no one knows exactly what that announcement will be, there are several probably rumors spreading about what Spears is up to.

A Las Vegas residency is reportedly in the works for Spears, and she may make an official announcement about her turn in the City of Sin.

Spears could also be announcing and/or performing a new single from her upcoming eighth studio album on "GMA." She has been training with a vocal coach and doing dance rehearsals for an upcoming project. The singer's Twitter has been teasing that she's hard at work for a few weeks. "Taking a quick break to say hi to all my tweeps :) Rehearsing for something top secret happening next week... #WERK," Spears tweeted on Aug. 28. Two days later, she followed it up with: "Just finishing up with my vocal coach & now I'm off to dance rehearsals. How's everyone's Friday? Where are you going for Labor Day weekend? :)"

Spears' publicist also addressed the rehearsals in an interview with Digital Spy. "Britney has been using a vocal coach and going to regular sessions and has also been working hard with her choreographer in preparation for what's coming up!" the rep told the publication.

Spears teased in an interview with Ryan Seacrest earlier this summer that her record should be due out by the end of 2013. Her first single is rumored to be called "Werk, Bi#ch."
