Here's Why Miley Cyrus Sticks Her Tongue Out So Much

Some of life's great mysteries may forever go unsolved. But at least, before the end of 2013, we have the answer to one.

Why does Miley Cyrus stick her tongue out so much?

Ever since Miley reemerged, like a majestic phoenix on a bit too much MDMA, into the public consciousness with her strange music video for "We Can't Stop," the former "Hannah Montana" star has been showing off a lot of skin...including her tongue.

Now, thanks to Barbara Walters of all people, we finally have a reason why.

"I get embarrassed to take pictures. That's actually the truth," Miley reveals in her upcoming interview for Barbara Walters' "10 Most Fascinating People" special. "I'm so embarrassed, because people are taking pictures of me, and I just don't know how to—I don't know how to smile, and just be awkward, so I stick my tongue out, because I don't know what else to do."

So there you have it. It's not a teasing gesture or a feminist statement. Miley's just shy is all.

The Barbara Walters special will also feature interviews with Jennifer Lawrence, Robin Roberts, the cast of Duck Dynasty, and others.
