Jennifer Lawrence doesn't worry about ageing.

The 25-year-old 'Hunger Games' actress has come to terms with the fact she can't stop "crows' feet" or her gender and is happy to "decay" like everyone else, because she believes if you constantly worry about growing old you won't be happy.

Speaking to Vogue online about her thoughts on maturing, the blonde beauty said: "I can't change my gender and I can't stop crows' feet, so I'm just going to move on and decay like everyone else.

"If you are worried about wanting to look younger when you're not, you're not going to be a very happy person. You just have to find other things to make you happy that are much more important."

However, the 'X-Men: Apocalypse' star - who has reprised her role as the mutant Raven in the science fiction film - has previously confessed she was conscious of her body and always feels like "the fattest one" among her fellow actresses, despite working out more than she would if she wasn't in the spotlight.

Speaking previously she said: "I would like us to make a new normal-body type.

"Everybody says, 'We love that there is somebody with a normal body!' And I'm like, 'I don't feel like I have a normal body.'

"I do Pilates every day. I eat, but I work out a lot more than a normal person. I think we've gotten so used to underweight that when you are a normal weight it's like, 'Oh, my God, she's curvy.' Which is crazy.

"The bare minimum, just for me, would be to up the ante. At least so I don't feel like the fattest one."

Meanwhile Jennifer's co-star Olivia Munn, who plays Psylocke, has revealed she dropped 12 pounds following the plant-based diet supermodel Gisele Bundchen swears by, and trained every day to prepare for her role in the fantasy sequel.

Speaking previously, Olivia said: "I started working out every single day, and then I also started getting into eating 20-80, where 80 per cent of your diet is fruits and vegetables and 20 per cent is whatever."
