Start the Britney Spears countdown. The "Work Bitch" is back.
The Grammy winner tweeted that her new track will premiere worldwide Monday, September 16 at 6 p.m. ET on iHeartRadio or your local radio station.
It will then be available at 12:01 a.m. September 17 on iTunes.
"Are u ready?!" she asked her 31 million Twitter followers.
Gosh, u better believe we are, girl.
She added the hashtag #YouBettaWorkB to her announcement tweet. Having seen the Britney Spears bikini photos she's been posting, she clearly is. B.
Her trainer Tony Martinez told E! News that Spears has been working out like a madwoman: "She's been a terror lately, working as hard as she can."
"Work Bitch" isn't the only new music coming from Britney.
Miley Cyrus announced on Tuesday, September 10, that she recorded a duet with Spears, titled "SMS (Bangerz)" on her upcoming Bangerz album.
"Now It's Britney AND Miley bitch! #TheyreNotReady for this @MileyCyrus... ;) #SMSbangerz", Brit tweeted following the reveal of Miley's track list.
Spears may have a point here. If it's anything like the production that is Miley Cyrus' Wrecking Ball ... we don't know if the Internet is ready for this.
