I'd say both Stevie and Linsey look their ages, BUT that is only b/c I am used to people looking younger then they are, both my parents look about ten years younger then they are, especially my mom, I think she stopped aging at 40! It is probably genetic, but a bit of lifestyle. As for me I still get asked what High School I go to, and I am over 20, although I will admit if I don't put make-up on I don't look old enough to drive, go figure. As for Stevie, of course she colors her hair
Although I got a kick out of seeing her grow her bangs out on the VH1 special, that is the most annoying experience as everyday is a bad hair day
