Sites are buzzing with the news that Nicole Richie and Joel Madden are taking their trip down the aisle on Saturday with E! News confirming some of the finer details, including the guest list and wedding dress.

Though neither Richie nor her fiancé Joel Madden have confirmed the wedding date, the website reports that the pair will be tying the knot at Lionel Richie's estate in Beverly Hills on Saturday.

As for Richie's dress, the site quotes an unnamed source who says she chose a Marchesa gown that "is custom-made, white, and cost her $20,000."

The guest list is set to include Ashlee Simpson-Wentz and DJ Samantha Ronson, who might be marching down the aisle as a bridesmaid.

Richie, 29, and Madden, 31, began dating in 2006. In addition to their daughter Harlow, the two have a 14-month-old son named Sparrow.

Since her days on "The Simple Life", Richie has kept busy adding accessories like sunglasses to her House of Harlow 1960 fashion line for the upcoming spring and fall collections for 2011.
