Nicole Richie Birthday with the fam

Nicole Richie and Joel Madden -- who are parents to two-year-old Harlow and 14-month-old Sparrow -- are reportedly planning to tie the knot in the first week of December. 
A source told X17online: "I heard Nicole Richie talking excitedly to Christina Aguilera about her upcoming wedding. She said, '29 days to go!'"

However, the nuptials will not be the only event the couple of four years will host, as they are also believed to be holding a "decoy event" to throw paparazzi off the scent of the real wedding. Nicole's close friend Christina Aguilera -- whom an insider has revealed is "practically living at Nicole's house" -- is also in talks with the pair to perform during their big day.
Meanwhile, it would appear the couple want the newly single singer to get out and have fun. Over the weekend Christina was spotted out with Joel, Nicole and Matthew D. Rutler, a set assistant from her new movie Burlesque.
An onlooker told E! Online: "The group was hanging out in a corner of the private club together. Christina and Matt were cuddling on a couch together and left holding hands."
