Perhaps Gwyneth Paltrow can teach the "Jersey Shore" cast a thing or two.

In an interview with England's Closer magazine, the 38-year-old Oscar winner -- who's a big fan of Guinness beer and red wine -- says she rarely gets sick after a night of too much drinking.

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 actress, who wed Coldplay frontman Chris Martin in 2003, adds that she's a lot more fun than people give her credit for.

"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,' ... maybe they will develop a different impression of me."
