Awww! This sounds like such a nice, low-key celebration!
Also in attendance at the dinner were Kate's parents, Carole & Michael Middleton, and her siblings James & Pippa Middleton!
Reportedly, the Duchess of Cambridge chose to have their housekeeper, Antonella Fresolone, cook for the night in instead of dining out!
"[It's] easier than going out and leaving George at home. She doesn't like a big fuss."
Awww! Low-key and simple! We love it!
Plus, duh she'd want to spend her birthday with her son! Any mother would!
