The reason? "I have a great hangover cure," she explains. "I take a cold shower in the morning and then I go into the sauna and drink a lot of water throughout the day. Green tea also helps!"
"The biggest misconception about me is that I am uptight," she shrugs. "I don't know why that exists, but I hope if people watch Glee that maybe they will develop a different impression of me."
