Kelly Ripa And Nick Lachey
Some famous people like to use Halloween as an excuse to dress up as other celebrities! Check out Kelly Rip and Nick Lachey and their costume in 2011. They were all decked out like Kim Kardashian and Kris Humphries had been on their wedding day. But the timing was very awkward. The day after this photo was taken, Humphries and Kardashian announced that they were getting a divorce!

Katy Perry
As you can see, Katy Perry is not really interested in sexy Halloween costumes. In 2016, she decided to go as Democratic presidential candidate Hilary Clinton. The singer did not hold back and even worse prosthetics to make herself look just like the politician. Clinton told Extra, “Oh my — look at that! This is shocking — oh, my gosh. This is great! She could be me when we finish the campaign.”
