Queen Elizabeth II meets rock royalty.

LONDON, ENGLAND - December 9, 2009

Lady Gaga and Miley Cyrus seemed to be in a battle over who could do the most to shock the queen.

They were among the performers at the Royal Variety Show in Blackpool, England.

Lady Gaga wore a red latex outfit with a 20-foot train.

She played her song "Speechless" on a piano that looked like it was out of a Dali painting that had legs 30 feet tall.

Cyrus wore the shortest of hot pants for her performance.

When it came time to meet the queen, she changed into an extremely low-cut gown showing off plenty of cleavage.
