Nicole Richie makes no plans to marry Joel Madden

Nicole Richie has no plans to marry Joel Madden.

The 'Simple Life' star – who has a 15-month-old daughter Harlow with the Good Charlotte rocker and another baby on the way – is focusing on her growing family, but hopes to wed "one day".

Speaking on US TV show 'Larry King Live' last night (28.05.09), the 27-year-old socialite said: "When I was a little girl I dreamed about getting married and that is definitely still a dream of mine one day.

"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."

The couple – who have been dating since 2006 – are eagerly awaiting the birth of their second child, but don't intend to find out the sex of the tot beforehand.

Nicole said: "We want the surprise. What is there really to plan? I'll get the clothes after." But Nicole's father Lionel Richie, who also appeared on the talk show, is hoping for a boy. The 'All Night Long' singer exclaimed: "Joel and I are having powwows. I want a grandson."

Nicole added: "You should here them prepping each other, wishing for a boy". It was Nicole and Lionel's first joint interview in six years. They also spoke about Nicole's stint in rehab for drug abuse in 2003.

Lionel recalled: "When she checked into rehab, her mother and I checked into rehab with her. Me and her mother Brenda spent a week in there with her. Tough love is very hard when you're in love."
