Washington, Mar 18 (ANI): Madonna is working on the last album in her contract with record label Warner Bros., and it will again be a compilation of her hits.
The 'Material Girl' will reportedly record new songs this summer, which will be meant specifically for the forthcoming release.
The swansong album, which is currently untitled, is scheduled for a release in September.
It will be her first hits album after 2001's GHV2, reports Contactmusic.
Madonna has previously released the 'Immaculate Collection' in 1990.
In October 2007, the Queen of Pop signed a lucrative deal of 120 million dollars with promoters Live Nation. (ANI)
