Sofia Vergara sent Reese Witherspoon to the hospital after filming accident

Working with Sofia Vergara on their comedy "Hot Pursuit" landed Reese Witherspoon in the emergency room.

During an appearance on Monday's "Ellen DeGeneres Show," Vergara admitted that she got a little carried away during one of her fight scenes with Witherspoon. "I sent her to the emergency room," the 42-year-old Modern Family star said proudly. "Something with internal bleeding."

After playing coy about the "secret" injury, Witherspoon elaborated, "I thought my appendix had burst."

Vergara further explained what went down during their on-screen altercation, and sort of implied it was her co-star's fault. "I pushed her and I pushed her and I kept telling her I think I'm pushing you too hard and she was like 'No, do it real,'" she recalled. 

The 39-year-old Oscar winner corroborated her co-star's story, adding, "I was like, 'Push me hard!'"

That's when it happened. "I was like this in the sofa," Vergara demonstrated, "and I popped her ovary."
