Nicole Richie is uncertain if she will ever marry her daughter's dad, Good Charlotte rocker Joel Madden.
The former party girl has reformed her wildchild ways since becoming a mother to her first daughter Harlow in January 2008.
But the Simple Life star admits she hasn't decided whether she will ever settle down by tying the knot with her boyfriend Madden.
She says, "I don't know about the future. I make it a custom not to plan the future. I may plan to and I may not."
It was recently reported that the couple are expecting their second child.
