Nicole Richie is planning to marry Good Charlotte singer Joel Madden this month, reports claim.

Madden confirmed that he hoped to make the Simple Life star his wife during a recent interview on US radio.

But she is rumoured to have already accepted his proposal and the pair will tie the knot in California on October 13.

Richie - who has reportedly signed up for an alcohol treatment programme - is due to give birth to the couple's first child early next year.
