While filming “Hot Pursuit” alongside Sofia Vergara, Reese Witherspoon had to learn the hard way that the “Modern Family” actress fights dirty. 

For a scene in the upcoming comedy, Vergara and Witherspoon’s characters had to push each other around. Unfortunately for Witherspoon, things got so rough that the actress ended up in the emergency room.

“Are you gonna tell them what I did to you?” asks Vergara during Monday’s (April 13) “Ellen” interview. “She went to the Emergency Room. I sent her to the Emergency Room.”

Witherspoon goes on to explain that, while they were fighting, she asked Vergara to push her harder. Unfortunately her suggestion backfired and she had to go the hospital after feeling like Vergara had burst her appendix.

“I popped her ovary,” Vergara chimes in.

When Ellen DeGeneres asks Witherspoon if her ovary literally popped, the actress jokes, “It’s clearly something that happens in Colombia … I don’t know what happened.”

Either way, enemies of Vergara’s should be warned that, if they challenge her, she’s a dangerous force to be reckoned with.

“Hot Pursuit” hits theaters May 8.
