Kate Beckinsale's sweet tooth often gets her into trouble - because she craves sugary treats.
The actress admits she can get hooked on chocolate and candy - and has to be careful not to over-indulge.
The Underworld star says, "When I'm tired sometimes I feel I am the closest I ever get to being a drug addict. I crave sugar."
And she has to watch whatever she eats and drinks - because her body reacts quickly to caffeine and alcohol.
Beckinsale explains, "I'm so sensitive I can't even drink a cup of coffee. I can't drink much wine. either. I'm a very cheap date.
"If I drank a whole glass of red wine I would have Chekhovian despair the next day."
