Miley Cyrus forgot the words to her own song while performing on UK TV show, Saturday Night Takeaway, this past weekend.

The Disney star appeared to stop singing half-way through new single Fly On The Wall and turn her back to the audience.

At the end of her disastrous set, the 16-year-old could be seen mouthing "Oh my God, I forgot my lines!" to one her dancers.

Miley had taken time out from filming episodes of Hannah Montana to fly by private jet for the TV appearance, at a reported cost of $300,000 to her record label.

A spokesman for Polydor says, "She always sings live so anything can happen.”

To be fair, Miley has had other things on her mind lately, such as being labelled a racist by Asian-American groups for pulling a 'slanty-eyed' pose for a photograph.
