Nicole Richie and Joel Madden are reportedly set to marry before the birth of their second child. Sources say the couple, who have a 1-year-old daughter Harlow, have already begun planning their wedding.

“They are old-fashioned in some ways. Now their second baby is coming, they both want to make it legal,” says an insider.

Richie has already picked out her wedding gown. The source adds Richie picked a vintage Yves Saint Laurent dress. “It’s been hanging in the back of her closet. She always planned to wear it on a very special occasion,” said the source.
