Opening with the forthcoming second single, '1+1' (which she performed on American Idol last night), the album is twelve tracks long and ends with first single 'Run The World (Girls)'.
There's only one guest listed — rumours of a Rihanna duet seem to be unfounded, unless she crops up on some kind of special edition — and that's Andre 3000, who is featured on a track called 'Party'. According to Wikipedia, 'Party' was produced by Kanye West.
Other collaborators include Babyface, Switch, Diplo and Ester Dean.
The album is out on June 27.
