Ashlee Simpson Left Red-Faced After Calling Britney Spears 'Trashy'  5/14/08

Ashlee Simpson was left more than a little embarrassed when she inadvertently called pop peer Britney Spears trashy in a recent radio interview.

Quizzed about her knowledge on London rhyming slang during a recent visit to the U.K., Simpson was asked what she thought the phrase, "You've had one-too-many Britney Spears" meant.

Unaware the term referred to someone who had drunk too much beer, Simpson offered her take on the phrase and immediately wished she had kept her mouth shut.

Speaking on British music show The Nokia Green Room, she recalled, "I was like, 'Oh, you've had one too many trashy girls!' And I was like, 'Oh my god, I can't believe I just said that! "It was really bad, I felt horrible."
