"We were in Prague and we signed plates for the restaurant. This is the 1st time I signed West!!" the 33-year-old reality star captioned an image, which was taken while she and husband Kanye West were still honeymooning in Europe.
Kardashian's post comes a week after she changed her name to Kim Kardashian West on both Instagram and Twitter.
Kardashian returned home from her honeymoon on Sunday, June 1, without West. The two tied the knot on Saturday, May 24 at Forte di Belvedere in Florence, Italy. They have an 11-month-old daughter named North.
