Second greatest hits compilation for Britney?

According to Gimme Britney, the record is due for September release and will include songs from two of her latest albums, Circus and Blackout, as well as six new tracks she is currently recording.
Earlier last month, Britney Spears was rumoured to re-release Circus. She reportedly gets helping hands from producer Fernando Garibay (Lady GaGa) and songwriters Olivia and Miriam Nervo (David Guetta).
While no statement is made by Britney’s camp concerning the rumour of her new project, the Womanizer hitmaker tweeted about working in studio with Max Martin in Stockholm. Beside recording new songs, she will also return to Canada and North America for a number of concerts with Ciara and Kristinia DeBarge as supporting acts.
Britney will start the gigs at Copps Coliseum in Hamilton, Ontario on August 20 and finish it off at Mandalay Bay Events Center in Las Vegas, Nevada on September 27.
In an interview with Entertainment Tonight, she said, “We have a song called Mannequin that we’re adding to the show, which I’m really, really excited about, so it should be interesting. We have to update  the show or it gets really boring.”
