I disagree strongly with the websites calling this a “freakout.”
A freakout is ripping your extensions out and beating up your guitarist with drumsticks while tearfully screaming at the audience “You just don’t get it! You just don’t love me enough!”
Having to hold up your strapless dress, forgetting the words to a song, and running offstage in tears is simply having a Blonde Moment. Hell, Dolly Parton split her dress right up the middle and merely borrowed a coat to go onstage to collect her Grammy; that, ladies and gentlemen, is the difference between a pro and a flash in the pan. Actually, come to think of it, Jessica’s the only one who hasn’t flashed lately. Give it five minutes, though.
