Jennifer Lopez - Jennifer Lopez Started Going Grey At 23

The singer/actress and American Idol judge insists on sticking to a strict styling schedule to avoid eagle-eyed paparazzi from catching her looking less than her best, although the star admits she's a little curious to see what her natural hair colour would look like now she's 41.

She tells People magazine, "I was prematurely grey at 23. I have to have (my roots) touched up every couple of weeks. I'm kind of tempted to one day just let it go. It'd be kind of exciting! Maybe someday we'll go really far away for like two months and I'm just going to see what it looks like."

But Lopez's hair confession hasn't affected her sexy status - she has just been named People magazine's most beautiful star of 2011.
