Mark Sept. 19, 2006, in your history books, folks.

We scoured through 500+ pages of Miley Cyrus photos to find the exact moment she broke the seal and became the tongue-wagging pop star we've grown to love -- or love to hate.

Just over nine years ago, Miley was still a 13-year-old moonlighting as international superstar Hannah Montana, and she was snapped poking her tongue out to the side while performing in San Jose.

Take a walk down memory lane, and check out Miley Cyrus' tongue through the years:

While Miley made her first foray in 2006, her tongue didn't see the light of day again until April 9, 2008, just before the "I Can't Be Tamed" fun really began.

The rest, as we all know, is history.

In 2013, Miley finally revealed the reason she always sticks out her tongue in an interview with Barbara Walters.

"I get embarrassed to take pictures," she said. "I don't know what else to do in front of the cameras."
