  • Bruce Jenner

    Bruce Jenner may have shot to fame after winning the gold medal in the decathlon at the 1976 Summer Olympics, but these days you can find him on reality TV with his wife, Kris Jenner, and the rest of the Jenner-Kardashian clan.

  • Apolo Ohno

    Apolo Anton Ohno has won eight Olympic medals for speed skating, but many people know him from his 2007 "Dancing With the Stars" win with dancing pro-turned-movie-star Julianne Hough.

  • Michael Phelps

    Michael Phelps has made many headlines in his career -- especially thanks to his record-setting swimming wins in the 2008 Summer Olympics -- but he also made the news when he was photographed using a bong in 2009. Hey, you're a real celebrity now, kid!

  • Shawn Johnson

    Gymnast Shawn Johnson tossed and tumbled her way to victory at the 2008 Summer Olympics, and then won "Dancing With the Stars" 2009. Gold and silver medals AND the mirror ball trophy? That's a lot of bling for such a young star.

  • The Winklevoss Twins

    Twins Tyler and Cameron Winklevoss competed in the 2008 Summer Olympics in rowing, but it's likely their dispute with Facebook founder Mark Zuckerburg -- and Armie Hammer's on-screen portrayal of them in "The Social Network" -- is what people remember them for. Plus, they have Aaron Sorkin to thank for that catchy moniker "The Winklevii."

  • Kristi Yamaguchi

    Figure skater Kristi Yamaguchi spun her way to gold in the 1992 Winter Olympics, and 16 years later was crowned the champion on "Dancing With the Stars."

  • Shaun White

    Two-time gold medal winner Shaun White has become the face of American snowboarding, and since flying to fame he's picked up several endorsement deals and even had a cameo in the 2011 film, "Friends With Benefits."

  • Kerri Strug

    If there was ever a celebrity-making Olympic moment, it would be Keri Strugg's 1996 Summer Olympics gymnastics win, when she performed on the vault with an injured ankle. It's a moment that will go down in Olympic history, and has made Strug a pop culture icon.

  • The Williams Sisters

    Aside from their many other tennis accolades, sisters Venus and Serena Williams took home gold in Women's Doubles in both the 2000 and 2008 Summer Olympics, and have made a mark in pop culture as well. When people started talking more about their off-the-court outfits, that's when they really made it.

  • Brian Boitano

    Figure skater Brian Boitano took home the gold at the 1988 Winter Olympics -- beating Brian Orser in what would become known as the "Battle of the Brians." He would later be featured as a recurring cartoon character on "South Park," and the song, "What Would Brian Boitano Do?" was featured in the film, "South Park: Bigger, Longer & Uncut."

  • Nastia Liukin

    Olympic gymnast Nastia Liukin went from winning medals at the 2008 Summer Olympics to sitting in the front row at fashion shows and even made an appearance on "Gossip Girl."

  • Tonya Harding

    And then there's two-time Olympian Tonya Harding. The figure skater became a household name not for her athletic talents, but for the out-of-the-rink drama she was involved with regarding a 1994 attack on fellow skater Nancy Kerrigan. A "celebrity" sex tape followed, securing her place in pop culture history, for better or worse, and she later pursued a short career in female boxing.
