Gwyneth Paltrow's hangover cure involves green tea and a sauna.

The 'Country Strong' star used to adhere to a strict macrobiotic diet but has eased the self-imposed controls on her lifestyle in the past few years and while she now professes a love for Guinness, Gwyneth doesn't worry about suffering any ill effects from alcohol as she claims to have the perfect solution to a heavy night.

Speaking about sometimes overindulging in alcohol, she said: "It's true. I admit it! But I have a great hangover cure. 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!"

Gwyneth - who runs lifestyle website Goop - admitted her uptight reputation does bother her and hopes her guest starring role in 'Glee' as fun loving substitute teacher Holly Holliday will show people a different side to her.

The 38-year-old actress - who is married to Coldplay frontman Chris Martin - explained to this week's Closer magazine: "The biggest misconception about me is that I'm uptight and I don't know why that exists, but I hope if people watch 'Glee' that maybe they'll develop a different impression of me."
