She's not known for being shy and retiring - so Miley Cyrus's excuse for her famous loose tongue seems a little bizarre.

The raunchy pop sensation claimed she actually sticks out her tongue because she gets embarrassed.

The former Disney child star, 21, who 'twerked it' all over Robin Thicke during a performance at the VMA Awards, said she famously bares her tongue because she doesn't know how to smile.

And it seems now she's started, she just Can't Stop.

During a chat with American broadcaster Barbara Walters as part of her Most Fascinating People of 2013 selection, Miley confessed: "I get embarrassed to take pictures. That's actually the truth."
