Nicole Scherzinger thinks that people "lose themselves to relationships."

The X Factor beauty - who split from Formula One racing pro Lewis Hamilton in June, ending their five-year relationship - finds that people often invest more than they should in their partner instead of living for themselves.

"Through the heartache it's been liberating. People lose themselves to relationships. You're living for the other person, putting so much in that you have to take a step back. Do things for yourself," she said.

Nicole wants to achieve more in her career before she settles down and has children because she plans to raise her children herself, like her mother Rosemary Elikolani did. "I definitely want kids - but not for a few years. My kids are going to be raised by me, the way my mum raised me. So I need to get my stuff out - albums, world tours, movies - and then try to do that," she added.
