9. Lady Gaga – 30
Lady Gaga is another singer that seems like she has been around forever, and she has been showing off her bizarre outlook on life for years. She even looks like she had been around forever, because her face is definitely older than her 30 years. There is no amount of makeup that can hide how mature she looks, and yet it does seem like it works for her. She keeps it hip and young by always changing her style.
