Nicole Richie Still Undecided on Her Wedding Dress

Nicole Richie says you can forget about all the rumors surrounding the designer she plans to wear on her wedding day.

It didn't take long for speculation to begin about Richie's wedding dress after she and her longtime beau, rocker Joel Madden, announced their engagement back in February. Some have even speculated that she would walk down the aisle in the same Monique Lhuillier gown worn by Molly Malaney on The Bachelor wedding, but the former Simple Life star insists she's totally clueless about her options.

"I have not decided on a dress," the mother-of-two tells InStyle.com. "I haven't even thought about it!"

With the recent launch of her Winter Kate clothing line and a new shoe collection for House of Harlow, the fashionista can be forgiven for not having the time to settle on her wedding attire.

Richie and Madden, who began dating in December 2006, are expected to tie the knot this summer.
