Pop superstar Beyonce rarely drinks alcohol because it just knocks her out cold.
The R&B star insists she can't handle her booze and, as a result rarely gets drunk.
She tells the China Daily, "I don't drink often. But when I'm drunk, I'm very quiet and I observe and I go to sleep. I don't think I'm much fun."
And, as for drugs, Beyonce has no intention of ever getting high - because she's far from impressed by the behaviour of drug users and abusers she meets in the music business.
She adds, "I always said I would never do it (drugs). I've never seen a person who was high and thought, 'Wow, I want to do that!'
"Im like, 'That's cool for them, but no thank you. I'll just have my wine.'"
