UPDATED: New greatest hits album?

Rumours are flying around that Britney is set to release another Greatest Hits album in Autumn of this year.

Greatest Hits: My Prerogative hit stores 2004.

Britney and her manager have already confirmed that they have been in the studio with legendary producer Max Martin whilst in Sweden. It is suspected this Greatest Hits will allow Britney time to spend with her family while recording more music for her seventh studio album.

Gimmebritney.com is reporting:

• The working title of the album is “The Singles Collection“. We’re led to believe that this may not be the final title.
• Sony Music have now officially added the release to SKU systems in Australia with a RRP of $29.95
• The release will be a double disc collection of her hits from the past 10 years
• "The Singles Collection" will contain more of Blackout and Circus tracks, than any of her previous albums. We’re assuming that the first disc will be focused solely on anything released before Blackout.
• There WILL be new tracks on the album. We’re not hearing the 6 new tracks as we previously heard, however we are being told that a single will be released from it – Radar is not getting released locally.
• The date is tentative on the SKU system of October 23rd 2009 – and will be released in Australia to coincide with her Australian leg of the Circus tour. We’re also guessing the new single will be released at this time as well.
