The Pussycat Dolls want a revamp

The Pussycat Dolls need an "evolution".

The group - who have been dogged by rumours they are set to split amid anger over Nicole Scherzinger's prominence in the band - insist they have no plans to go their separate ways, but do need to make some changes.

Singer Melody Thornton said in an Australian interview: "It's good news for our fans. I don't think we're breaking up any time soon. As long as this thing is moving, we're all still here. The reviews say a lot about the need for an evolution within the Pussycat Dolls.

"Nicole's always had extra things going on as opposed to the rest of us, but we have aspirations as well. It's definitely a huge misconception that we are just chilling and happy to just be members of the group."

One person who could be brought in to freshen up the line-up is Lady Gaga - who has been opening for the 'Don't Cha' stars on their current tour - after Melody spoke of her admiration for her.

She said: "Lady GaGa is bringing something new and fresh. I think she's amazing."

It was previously claimed that Nicole is set to announce she is quitting the group at the end of their tour in a bid to focus on her solo career.

Her plans became apparent after the group's version of 'Jai Ho' was released under the name Pussycat Dolls featuring Nicole Scherzinger.

On their tour, Nicole performs their latest song 'Hush Hush' on her own while the other girls are off stage.

Speaking about the name change, US blogger Perez Hilton said: "The big reason most people believe is that Nicole has actually now LEFT the Pussycat Dolls but is still remaining with them until the 'Doll Domination' era is over."

The band's record label Interscope have so far refused to comment on the speculation.
