If pregnancy rumors start "Catching Fire" for Hunger Games star Jennifer Lawrence, we'll know why!

The 23-year-old Oscar winner had an unfortunate slip of the tongue in an interview with YourTango.

The site asked J.Law about her toughest stunt on the set of Catching Fire.

"There's a scene where we're hanging on to a spinning clock in the middle of a river," the actress explained. "It was hard because this wheel was going 30 miles per hour in freezing cold water. I had morning sickness."

That's when her interviewer interrupted with the response we'd all have: "WHAT!"

"Oh no! I mean, motion sickness!" Jennifer blurted. "Oh my god! Now, the morning sickness rumors are what I'll be dealing with for the rest of the month. I will say on the record that it was tough to keep the cookies down, but it wasn't morning sickness! It was motion sickness!"

It wasn't Jen's only digestive troubles recently. She detailed a trip to the ER on The Late Show With David Letterman last night, November 20.

"I thought I had an ulcer, and it turns out it was a fulcer," she quipped. "I just had this really bad pain for, like, three weeks, and you can only sh—t your pants so many times a day before you have to go to the emergency room … I just did this thing yesterday where they did an endo-scopo-something."

We have no idea what Jen's family aspirations are, but we're guessing that after these two bouts with tummy troubles, she's not eager to have any morning sickness!
