Jennifer Lawrence might be known as the “Girl on Fire” from the Hunger Games series, but the Hollywood star credits junk food and “Keeping Up with the Kardashians” for her phenomenal physique.

The “Silver Linings Playbook” star admitted that she’s a couch potato. Instead of hitting the gym or partying with friends, the 22-year-old actress said she prefers to lounge all day.

"I don't like going out that much. I'm kind of an old lady," Lawrence told Marie Claire South Africa in its January issue.

"After it's 11, I'm like, 'Don't these kids ever get tired?' When I'm out, I think about my couch. Like, 'It would be awesome to be on it right now. I bet there's an episode of 'Dance Moms' on. Am I missing a new episode of Keeping Up with the Kardashians?"

She added, "I'm just stressed by the idea of missing them."

The self-proclaimed “old lady” said she loves having gatherings at her two-bedroom apartment in Los Angeles, where she serves guests bowls upon bowls of junk food.

"I like people to come over to my place," the Golden Globe-nominated actress told the magazine. "It's like a reality TV show cave. I just learned how to work TiVO. That changed my life."

"Reality TV is my silver lining," Lawrence joked. "At the end of the day there's probably nothing that makes me feel better than junk food and reality TV."

Her latest film, “Silver Linings Playbook,” premiered in theaters on Christmas Day. The movie also stars Bradley Cooper and Robert DeNiro.
