Lindsay Lohan is sooooo over Red Bull - the actress has found a new way to get her calories in liquid form.

The Mean Girls star – who has been looking worryingly thin of late - has revealed that she likes to fill up on brain and body-boosting energy drinks.

“I drink so much of it - I love it,” she says of the Neuro brand of beverages, according to Life & Style magazine.

“There are several kinds, including Neurogasm, which is for sex. But I don’t need that one right now unfortunately.”

As well as being a fan of mood-enhancing Neurosonic, she has also been spied knocking back the Neurotrim, which as the name suggests, is supposed to dampen hunger pangs and kick-start the body's fat-burning mechanism.

An onlooker said: “I saw her driver tuck a bottle of something into his pocket before she went in [to L.A. night spot Bardot]. Lindsay said to him, ‘You don’t need to hide it. It’s just my Neuro.’”

Lindsay should try eating food sometime, it tastes delicious!
