Jennifer Lawrence expects hosting 'Saturday Night Live' to be the ''most amazing experience'' of her life.

The 22-year-old actress is the guest presenter on the famous comedy show this weekend and though people she knows who have previously been on the programme, such as her 'Silver Linings Playbook' co-star Bradley Cooper, no one had prepared her for how much fun it would be even just at the rehearsal stage.

Asked if anyone had given her advice, she said: ''No, they didn't. They should've. They've just said it's going to be the most amazing experience of my life, which they were right about.

''Oh my God, it's been amazing. I don't think I've ever laughed this much in my entire life. It's just been incredible.

''It's just amazing working with people - their job is just to be funny all day every day. You are in a room with some of the funniest people in the entire world.''

Jennifer isn't afraid to act like an ''idiot'' in the sketches on the show, but insists none of them will involve revisiting her 'Hunger Games' character Katniss Everdeen.

She told 'Access Hollywood': No, I retired my bow and arrow for this weekend.''

Asked what fans can expect, she added: ''Me, acting like an idiot. A lot.''
