After all, the name Kim Kardashian is known around the world! "Kim West" sounds like a female bull rider. (OMG, we have a GREAT idea for a movie!)
"We were in Prague and we signed plates for the restaurant. This is the 1st time I signed West!! Xo."
But that could have been just trying it out, seeing how it felt. A signature on a plate is temporary; for the real test of permanence, you have to turn to Twitter!
And there you have the ultimate proof: Kim changed her Twitter name:
We guess Kim is feeling more secure with this marriage than her previous ones! Otherwise she'd be Kim Kardashian Thomas Humphries West!
And that name is NOT going to fit on a perfume bottle! LOLz!
