It could have been Hunger Pains.

Oscar-winning actress Jennifer Lawrence looked stunning on the red carpet at the Los Angeles premiere of “The Hunger Games: Catching Fire” on Monday — but she wasn’t feeling so hot on the inside.

A source tells us that the charming Lawrence — who doesn’t hide her penchant for fatty food and french fries — received medical attention sometime before the screening of the blockbuster because her tummy hurt.

“She had a brief doctor visit sometime before the premiere,” says our source. “She had cramps and stomach pain. Turns out it was gas.”

Our source adds that Lawrence also missed the after-party and was told the actress was feeling “under the weather.”

“One of the film producers threw a party at his place last night and her stomach was the topic of discussion,” says our source.

Her rep Liz Mahoney from ID-PR declined to comment.Lawrence’s absence didn’t keep 1,500 fans from hitting another “Hunger Games” party, held on a rooftop across the street from Nokia Theatre screening.

And J. Law appears to have bounced right back to health. The “Silver Linings Playbook” star was scheduled to appear on the “Late Show with David Letterman” Wednesday night, then hit the New York “Catching Fire” premiere at AMC Lincoln Square.

Lawrence isn’t one to be embarrassed by this kind of thing – previous stumbles, like when she tripped at the Oscars, have only added to her charm. Remember, she’s the one who asked her “Hunger Games” co-star Josh Hutcherson how his “rash” was doing on a red carpet.

True to form, the 23-year-old didn’t hold back during a recent appearance on Conan O’Brien’s show, where she fessed up about her crush on John Stamos.
“I turned into a perverted guy, I was following him into rooms and staring at his a–,” she said. “I just started really freaking out, and he asked me if I was on mushrooms, and I was like, ‘No, I am dead sober. This is just me.’”

This week, Lawrence pointed out how odd it is that her new pixie cut made headlines across the globe, saying, “Terrorists probably know about my hair cut.”
Well, Jennifer, now they know about your gas too.
