Oh, wow! It's happening so soon!
The ceremony will take place at Richie's father Lionel's Beverly Hills home in front of 75 guests - including Christina Aguilera and Samantha Ronson - and the proud poppa will also be walking his daughter down the aisle!
Meanwhile, Nicole's best friend Masha Gordon will serve as maid of honor, Joel's brother Benji is best man, and little Harlow will be the flower girl!
The insider also reveals:
"Christmas has always been about family and faith for Nicole and Joel, so there is not better time of the year for them to wed. Nicole and Joel will spend Christmas with their family after the wedding, before heading off on honeymoon."
It sounds like it's going to be an absolutely LOVELY and intimate ceremony!
We're so thrilled to hear that these two are finally tying the knot!
Congratulations, you two! Best of luck with the rest of preparations!
We just KNOW it's going to be beautiful!!
