Kylie Jenner may be 18 years old, but she’s still on the cusp of being considered a teenager and an adult.

This would be considered a smart business move if there wasn’t another famous Kylie who has been around much longer using the same name, Kylie Minogue. If Jenner is successful, this means the pop icon would have to pay the reality starlet royalties for using her own name.
