Baby Duke broke his St. Patrick's Day best!

Mom Giuliana Rancic posted a too-cute photo of her and Bill Rancic's precious son — and his newly acquired facial hair — on March 17.

Duke, almost 7 months, donned a hilarious green mustache with an even funnier facial expression. “Happy St Patrick's Day from Baby O'Duke. #25percentirish,” G wrote along with the photo.
