Nicole still not sure of tying the knot with Joel

Washington (ANI): Hollywood socialite Nicole Richie has revealed that she's not sure she will marry her daughter's dad, Good Charlotte rocker Joel Madden. Though the Simple Life actress has reformed her wild partying ways since giving birth to daughter Harlow in January 2008, she has still not made up her mind about tying the knot.

Nicole, who is expecting her 2nd child with Madden, revealed that she doesn't believe in planning her future. "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," Contactmusic quoted Nicole, as saying.

Meanwhile Nicole was also in news for appreciating Christina Aguilera, as she called her a great mother, great wife and a great entertainer.
