In the picture, the 33-year-old is signing a plate for a restaurant with her new name. "We were in Prague and we signed plates for the restaurant," Kardashian captioned the pic, "This is the 1st time I signed West!! Xo."
North West's mom appeared to have practiced the signature, as a napkin sits on the table with "West" written on it.
"Had the best most relaxing romantic honeymoon in Ireland & Prague!" Kardashian tweeted upon her return from Europe on June 2, "Missed my baby girl so much! Excited to be home to squeeze her so tight!"
