Kim Kardashian told everyone on her TV show that she has a tattoo inside her lip. It's a little picture of the infinity sign, which means forever. She got it after she was the host of a show called "Saturday Night Live."
Kim's friends all got tattoos too, but they put theirs on their hands. Kim didn't want hers where everyone could see it. She once said that she would never get a tattoo because she's like a fancy car that doesn't need stickers.
The tattoo is special to Kim because it reminds her of the fun time she had on TV. She doesn't see it much, only sometimes when she's brushing her teeth. It's a little secret that she has, showing that even someone as famous as Kim has surprises.
