This 3-week-old tot is also going to have an awesome godmother: Simpson's rep confirmed to E! News Thursday that CaCee Cobb will fill this special role.
CaCee, who is engaged to longtime beau Donald Faison, has been a close friend of Jessica's for many years.
She was originally Jessica's personal assistant and has appeared alongside her employer-turned-BFF on MTV's Newlyweds and VH1's Jessica Simpson: The Price of Beauty.
And with any luck, Maxwell will get to grow up with her godmother's future kids.
"All my friends are having kids right now and it's kind of like you want to have your babies at the same time," CaCee told People in December. "I can't imagine my kids not growing up with Jessica's kids."
