She burst onto the scene as a dark-haired, bright-eyed girl next door. After winning the role of Rachel on Friends, Aniston caused a hair phenomenon in 1995 when her updated shag was copied by women everywhere.

Now a full-blown movie star, the Marley & Me actress keeps it long, shiny and very sophisticated. Aniston does, however, like to play around with color—lip color, that is. Says makeup artist Robin Siegel, "I've used so many different colors on her—pinks, reds, browns. Jen likes to experiment!"
