Richie, Madden may wed this weekend

It is thought that Nicole Richie and Joel Madden will finally get married this weekend.

Gossip Cop claims that the couple will have a small ceremony this evening with family and friends.

According to reports, Richie has yet to decide between a Monique Lhuillier dress and a vintage Chanel dress for the event.

Richie and Madden have been together for over four years and have two children together, 2-year-old daughter Harlow and and 1-year-old son Sparrow.

The couple announced their engagement at the beginning of 2010, but details about the wedding date have been kept quiet from the press.
