She told Ryan Seacrest that pre-Grammys, she had a minor dress snafu. When she tried her white gown on, she discovered that it was totally see-through. While most under-25s in Hollywood would have slapped a leotard on underneath and wore it proudly, she instead opted for the very pretty and tasteful navy feathered frock by Romona Keveza.
