Jennifer Lawrence has joked she still has "meltdown potential".

The actress has become one of Hollywood's biggest stars since playing Katniss Everdeen in The Hunger Games.

Jennifer likes to shun the limelight when she's not filming, but insists it's always possible that she could go a little wild in the future.

"Eat junk food and watch reality TV. I'm kind of an old lady, aren't I?" she mused in an interview with British magazine more!

"But being young means I still have that meltdown potential to come, so stay tuned...."

The 22-year-old star also spoke about the furore surrounding Kristen Stewart and Robert Pattinson. Kristen admitted having an affair with married director Rupert Sanders and speculation about the state of her relationship with Robert has been rife since.

Jennifer says the situation highlights the downsides of fame.

"I think it's heartbreaking when somebody's whole life is in the media to the extent that she has a human moment and it is exploited like that," she said.

"There are lots of elements to fame that are scary. Me, I'm just kind of going to go with it and keep my fingers crossed!"
