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."
