The girl group's creator Robin Antin recently revealed that she was in the process of recruiting a collection of new females to reboot the pop troupe, which was previously fronted by Nicole Scherzinger.
Bennett - who featured on LMFAO's summer smash 'Party Rock Anthem' - has now ended speculation that she would be unveiled as a Doll by confirming her hiring.
She told Billboard: "We're currently figuring out who's in the group and we're working on an album."
It is expected that the full lineup will be unveiled sometime in the New Year ahead of a new single from the refreshed Pussycat Dolls.
