Nicole Richie is reportedly lining up her bridesmaids for her wedding to longtime boyfriend and father of her two children, Joel Madden. The short list might be a little surprising.

DJ Samantha Ronson might be marching down the aisle as a bridesmaid, according to E! News, and the couple's two-year-old daughter Harlow will serve as the flower girl.

The website reports that the pair will be tying the knot at Lionel Richie's estate in Beverly Hills in December. However, the couple has not confirmed any wedding plans.

Madden Tweeted about the couple's engagement earlier this year saying, "Yep. i'm engaged. Very happy. Yeah we've been engaged for a while so your all kind of late on that. But Thanks for the hooplah all the same." He quickly deleted the post but it was already picked up by a few news organizations including People magazine.

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.

In the mean time, Richie has kept busy adding accessories like sunglasses to her House of Harlow 1960 fashionl line for the upcoming spring and fall collections for 2011.

"I have been traveling all over the world, meeting with buyers, doing appearances and meeting my customers to get their feedback," Richie told Women's Wear Daily according to People. "Now I feel I know them very well, and have been designing for them."
