Lily Allen has spoken about her past relationship with drugs – and said she can't say that she'll never take them again.

Speaking to a US magazine, the singer admitted that she isn't “a good person” when under the influence.

“I won’t say I’m never going to do drugs again,” she added.

Allen also spoke about being carried out of the Glamour awards in London in June, and said she fears someone may have spiked her drink.

“I can’t believe I got into that state. It makes me believe somebody put something in my drink,” she said.

Her comments were published shortly after she was seen allegedly punching a member of the public following a night out in London.
