Nicole Scherzinger Calls Pussycat Dolls Lineup Shifts 'Inevitable'

'When it comes to girl groups, I think we did the best that we could for a good chunk of time,' she tells MTV News.

With the search on to fill out the Pussycat Dolls lineup after several members left the group to pursue other interests, the only surviving Doll, Nicole Scherzinger, admits that changes within the group are "inevitable." But Scherzinger insisted that all the girls who left are like family to her, and she only wants them to find success and happiness in their new careers.

"You know what? I've always looked at the Pussycat Dolls as a family," she told MTV News. "We were really a sisterhood. We were together for six years, nonstop, 24/7. And I know a lot of them are pursuing their own solo projects and future endeavors, and I wish them nothing but the best."

While she's still fully committed to the girl group, she knows that people sometimes need to move on to find their own happiness. "I believe they are beautiful and talented girls. And I believe in them, and I just want them to be happy," she said. "Success means different things to different people, so whatever brings them happiness, I wish them that."

Still, she knows that in the world of girl groups, breakups and shakeups are the norm. "It's kind of inevitable, right? When it comes to girl groups, I think we did the best that we could for a good chunk of time," she explained. "We had an amazing time, and then people change and people grow, and sometimes things aren't right for them. We're all artists — just go and be creative. I love the PCD. It's been a blessing for me. I don't take it for granted, so I can't wait to do more music."

Aside from PCD, Scherzinger will also be strutting her stuff on the upcoming season of "Dancing With the Stars."
