Nicole Richie not ready for more kids

London: Fashion designer Nicole Richie says she and husband Joel Madden are far too busy right now to add to their family. The 30-year-old socialite hasn`t ruled out having more kids but says she is busy raising daughter Harlow, four, and son Sparrow, two, reported a website.

"I`m not ready for baby number three - it`s not something I`m discussing with Joel at the moment, but maybe we`ll have another child sometime in the future. It`s a full time job taking care of two children but they mean everything to me. It`s hard to balance being a full-time mum and having a career, but somehow you manage," Richie said.

The socialite, who has previously battled drug addiction, believes becoming a mother helped her turn her life around.

“Being a mum has changed me for the better - they`re my number one priority. Nothing can prepare you for that kind of responsibility," she added.
