Meanwhile, Nicole recently chatted with press about the idea of marrying boyfriend/babydaddy Joel Madden.

“When I was a little girl I dreamed about getting married and that is definitely still a dream of mine one day,” she explained.

The couple who have baby girl together, Harlow, and also another one on the way, feel that a wedding is not on the top of the list of priorities.  “But right now, we’re really, really focused on our family, we’re focused on our foundation and as far as feeling that need of commitment, we both really have that in each other.”

And what is the word on the expected baby? A pregnant Nicole wants to keep the sex of her child a secret. “We want the surprise. What is there really to plan? I’ll get the clothes after.”
