Teenage girls are all steamed up these days about straight hair. The steam iron is replacing the huge rollers on which countless teens slept every night to achieve the height and curls fashionable until. The same girls endure having their hair stretched to absolute straightness on the ironing board, and then ironed to keep it that way. Unlike the roller setting, this takes teamwork. Gay Stilley, 14, goes through an ironing session with a couple of her friends at the Stilley Home in Glen Oaks, Queens, New York City on December 23, 1964. With a wary eye, Gay tries to watch the straightening process as one friend stretches her hair with a comb and another does the ironing, in the Stilley kitchen. (Photo by Marty Zimmerman/AP Photo)

“Former Harry Potter star Emma Watson has shed her squeak-clean image by parading the streets in a bra and hot pants for her role in Sofia Coppola's latest movie. The actress has signed up for a leading role in The Bling Ring, playing one of the real-life teens who stole from the homes of stars including Paris Hilton, Lindsay Lohan and Orlando Bloom in 2008 and 2009. A series of images from the Los Angeles film set are set to shock the Brit's younger fans as she has been photographed strutting in tiny shorts, a bra-style top, leather jacket and towering high heels”.
