40 Celebrity Doppelgängers We Can't Tell Apart

Did you know...

• Jennifer Aniston's star-defining role on friends started a hair craze in the 90s that even lasted into the early 2000s. Called "The Rachel," Aniston's shoulder-length haircut had grown-out bangs and highlights styled to perfection. A hairdresser in Detroit noted that at the peak of its popularity, 40% of her business was devoted to recreating "The Rachel." Too bad that it was notoriously difficult to maintain on your own at home.
• In the summer of 2007, Joh Hamm became a household name when Mad Men premiered to critical acclaim and strong ratings. Just over a year and a half later, Ellie Kemper stole America's hearts (and Dwight's and Andy's) when she became the new receptionist on The Office. Before they were famous, Hamm was Kemper's high school drama teacher!
• When Rihanna debuted her famous red locks in 2010 (around the same time she was featured on Eminem's "Love the Way You Lie"), she started a red-hair trend. Over the next twelve months, she changed her hairstyle 13 times—more than once a month! But that came at a pricey cost. Sources say the annual price tag came out to $1,168,000 on just her hair.
• Björk created a media sensation when she wore her iconic white swan dress to the 2001 Oscars. At the time, many derided it as hideous and a publicity stunt, but it has since gone down as one of the most memorable dresses of all time—even if it isn't exactly beloved. She says David Bowie was the inspiration behind the dress.
• Jackie Kennedy is famous for redecorating and renovating the interior of the White House. Actually, on just her first day, she ordered $50,000 in changes for new rooms for the children and upgrades to the kitchen. She later hosted a tour of the White House for CBS News which was viewed by 56 million people and won her an Emmy Award.
