The singer is the only remaining original member of the group but insists she has no idea what the future holds for them, despite founder and manager Robin Antin recently hiring four new women to join Nicole.
When asked about the rest of the group being recast, Nicole said: "I don't know what's going on with that. There's always the speckles [speculations].
"There's the Dolls from the lounge and Vegas and all that, so I'd say everyone is a Pussycat Doll actually."
Seemingly alluding to how she was purposefully being vague, Nicole then added: "Do you like how I'm answering these questions?"
Robin has previously said the group are on a break and will return with a new line up consisting of Nicole alongside Vanessa Curry, Kherington Payne, Rino Nakasone Razalan and Jamie Lee Ruiz.
The most famous line up of the Pussycat Dolls – which included Ashley Roberts, Melody Thornton, Kimberly Wyatt and Jessica Sutta alongside Nicole – broke up last year after Melody and Kimberley spoke of their unhappiness in the group and were critical of Robin and their management and how they perceived Nicole as receiving preferential treatment to them.
