Britney Spears is rumoured to be in talks to release her own fitness DVD.

The Toxic hitmaker piled on the pounds after giving birth to her two sons, but recently returned to her previously svelte figure with a gruelling exercise regime and healthy diet.

And now the singer reportedly wants to share her fitness secrets with the world by making her own workout disc.

Although representatives for the star insist a deal has yet to be signed, a spokesperson for her Jive/Zomba label tells U.S. newspaper the Chicago Sun-Times, "The idea makes perfect sense, given Britney is a singer who uses dance so much in her act."
