Actually Sam, Britney has been recording for a year now after her Circus Tour ended. These are the producers and writers that she's been working with,

1. Bloodshy & Avant – “Radar”
2. Max Martin – “3″
3. Danja – “Gimme More”
4. Sean Garrett – “Toy Soldier”
5. Rodney Jerkins – “Lonely”
6. Nervo Sisters
7. Scott Storch
8. Rusko
9. Ryan Tedder
10. Fraser T. Smith & Livvi Franc
11. DJ Tiesto
12. Kerli
13.David Guetta????
14.The Outsyderz – ‘Womanizer”
15.Soul Diggaz – (songwriters) – “Get Naked”
16. Marcella Araica- (songwriter) – “Perfect Lover”
17. Jon Asher??
18. Fernando Garibay – “Amnesia”
19.Russ Castello
20. Dr. Luke – “Circus
21. Sia - confirmed to be writing songs for Britney
22. Akon - Recently confirmed by a Reagge artist/group called "Predator Dub Assasins AKA P-Dub)

So she's been in the studio but "DISCRETELY". And also she has a studio in her house. So I'm sure she's always recording when she has the chance.

So I'm guessing we could get new music during the 4th quarter. :)
