A demo recording of Britney Spears reportedly singing Lady GaGa's hit track TELEPHONE has leaked on the internet.
Gaga's song, which became an international smash hit upon its release this year (10), was originally written for Spears, and a recording, which purports to be the Toxic hitmaker testing out her own version in the studio, emerged online over the weekend (01-02May10).
The four-minute track first surfaced on iLeaks.com, amid reports the recording was made before Spears rejected the track and handed it back to Gaga who included it on her recent The Fame Monster album.
