Former athlete Caitlyn Jenner has revealed that she keeps her Olympic gold medal in her makeup draw as opposed to displaying it in her home.

The 65-year-old, who became a transgender woman earlier this year, took decathlon gold in the 1976 Summer Olympics in Montreal.

During a video post on her blog The Real Me, Jenner, formerly known as Bruce, answered a fan who asked where she kept the winning medal.

"My gold medal is my most prized possession - I'm so proud of it," said Jenner. "However, I never wanted my kids to feel like they had to have a gold medal in order to be considered a success.

"I didn't want them to constantly compare their own achievements to my time in the Olympics, so I haven't displayed my medal."

Jenner, who was honoured with the Arthur Ashe Courage Award at the ESPYs last month, is now the star of her own E! reality show I Am Cait.
