Jennifer Lawrence doesn't envy Kristen Stewart's fame.

The 21-year-old actress is set to become a household name thanks to her forthcoming role in 'The Hunger Games', but says she would hate to be as well known as the 'Twilight' star.

She said: ''I look at Kristen Stewart now and I think, 'I'd never want to be that famous'.

''I can't imagine how I'd feel if all of a sudden my life was pandemonium.''

But Jennifer - who is dating her 'X-Men: First Class' co-star Nicholas Hoult - admits the positives far outweigh the negatives when it comes to her career.

She told Britain's Glamour magazine: ''In some ways, it's a hard life, but it's a great professional life.

''I'm doing what I love, and then I get months and months of rest. I have a lot of money for a 21-year-old. I can't stand it when actors complain.''

Having pocketed a rumoured £320,000 for the first 'Hunger Games' film, Jennifer has been learning to loosen the purse strings and allow herself treats from the hotel minibar.

She said: ''Just recently I started letting myself eat things from the minibar. When we were kids, we would never open the minibar. A $6 Snickers bar? But the other day I was in a hotel and I was staring at a Snickers bar, and I finally just ate it.

''Then it was like something In Me snapped. I opened all these drinks. I thought, 'I can do it now'. Now I'm all grown-up I can eat things from the minibar.''
