'The X Factor' judge - who previously claimed she sang 95% of the girl group's songs alone - claims the idea of getting back together with her old bandmates ''sounds really cool'' and she would be open to it in the future.
The 34-year-old 'Don't Hold Your Breath' singer told Kiss FM in a new interview due to air on Thursday (24.01.13): ''I love the girls, I miss them, I wish them the best. I don't see why it wouldn't be possible sometime in the future.
''But right now I'm really excited for all the hard work I put into my music to get that out.''
Nicole was previously accused by her former bandmate Kaya Jones of refusing to share the spotlight with the rest of the Pussycat Dolls.
Kaya did not deny Nicole's claims that they didn't perform any of the vocals but insisted the other members of the band were heavily involved.
She said: ''There was a lot more going on behind the scenes. Nicole was always someone who wanted to be in the spotlight and would do pretty much anything to get it.
''To call the other girls in the Pussycat Dolls 'window dressings' is a bit far-fetched ... every girl in the group was talented.''
Nicole said: ''I hope I don't get in trouble for the stuff that I say but I'll never forget I finished the album, 'PCD', and [executive producer] Ron [Fair] and I brought the girls into the studio and we played it for them. It was the first time they'd ever heard the music.
''Do you understand what I'm saying? We played the album for the Pussycat Dolls. It was the first time they'd ever heard the songs.''
