Miley Cyrus was anything but reserved when meeting the Queen at Monday's Royal Variety Awards in London.

Cyrus, 17, sported what London's Daily Mail dubbed the "daring outfit of the night" - tiny leather hotpants and a crop top - while performing at the star-studded event.

Later, while saying hello to the Queen, she slipped into a cleavage-baring orange dress.

Cyrus recently turned heads by revealing a tattoo that reads "just breathe" under her left breast.

The "legal age" to get inked in the U.S. is 18 -- but the teen may have gotten a permission slip from her parents.

Some blogs have speculated that the tattoo is in honor of her friend who died of Cystic Fibrosis. But Cyrus' rep has yet to comment.
