Speaking to the December issue of Marie Claire magazine about Hamilton, Nicole said: "Yeah, [the relationship] does keep me grounded.
"Lewis and I are a team and we’re really there for each other, and the time we spend together I do cherish. It’s separate from everything else."
She went on to dismiss the idea of being a 'celebrity couple' likeKim Kardashian and Kanye West, stating: "I know there are a lot of relationships who, you know… Take Kanye and Kim [West and Kardashian] – well, they’re perfect for the cameras. Lewis and I are a bit more subdued."
The X Factor judge also claimed that despite being loved-up with Lewis - she doesn't plan on starting a family with him just yet.
Nicole explained: "I’m not getting any younger. I don’t want to have kids now, though. When I’m a mum, I’m not going to be one of those mums who has nannies. Actually, I might have nannies – never say never – but I’m not having someone else raise my kids.
"I think five years might be a good time to look at having children, but I think whenever it’s meant to happen is when it will happen. Right now, I’m focussing on my career."
When asked if she sees her age as an issue, Scherzinger replied: "I see lots of women having beautiful children later in life now. And, if not, just freeze your eggs!"
She explained: "I went to a club with my friend, Will.I.Am, and talked to my friend, Chris. They got those pictures and now everyone thinks one thing and it’s not the truth. It makes you feel like you can’t do anything.
"I’ve known Chris since he started in the business. He’s like a little brother [to me]. He’s one of the most talented people in the industry."
Scherzinger then refused to answer further questions regarding the public perception of Breezy following his 2009 assault on then-girlfriendRihanna, concluding: "I honestly just don’t want to address the Chris thing, if that’s alright."
