The `Poison` singer has been dating Formula 1 champion Lewis Hamilton for three years, and admits she is ready to take their relationship to the next level as she hopes to eventually start a family with the 25-year-old sportsman.
She said: "I`d want to be married before we have kids and that`s something we`ll hopefully be doing soon. I would love to have a couple of children."
Nicole had a stint as a guest judge on UK TV talent show `The X Factor` earlier this year and admits she would give serious consideration to an offer to join the panel of the US version of the programme when Simon Cowell launches it next year, though she is content with her music career if she is not approached.
She told Closer magazine: "If Simon were to ask me, it would be something I would have to think about, but right now I am really focused on my music and my album.
"I had so much fun with Simon and Louis Walsh when I was on the show, so I guess anything could happen! I do everything from my heart."
As well as Nicole, current UK programme judge Cheryl Cole has been linked with a role on US `X Factor` and the former Pussycat Dolls star believes the British beauty would be a great addition to the panel.
She said: "I would never think about Cheryl as competition. I think she is really amazing in her job and would be well received in the US."
