Julia Roberts – 51

Julia Roberts became an in-demand name in Hollywood back in the 1990s, thanks to her movie, Pretty Woman. She later had notables performances on  Erin Brockovich, Notting Hill, and The Normal Heart. Roberts has been rocking her beautiful blonde hair in recent years but in case you didn’t know, she is actually a natural born brunette. You can just imagine how often she must visit the salon just to maintain her blonde look. Roberts’ latest role was in the show called Homecoming. She is currently set to do a new film called Little Bee.
