American singer Fiona Apple's top tip for chilling out is allowing snails to crawl all over her.

The Grammy-winning artist will never need a therapist as long as she has her slimy chums to calm her down in times of trouble.

She says, "The thing I love is snails. The most calming thing to me is to have a snail crawling on me.

"It's like I've been put in my mother's arms and rocked. I just feel really relaxed.

"This guy I used to go out with, we had this terrible fight.

"We were outside and I saw a snail. I picked it up, put it on my arm, and carried on the fight with the snail on me. And I was OK, I could calm down."
