VIDEO : Sofía Vergara and Reese Witherspoon Talk 'Hooking Up' in Hot Pursuit

Reese Witherspoon had to endure some real pain while filming Hot Pursuit.
Not only did she end up spending a night in the hospital after Sofía Vergara accidently caused her to pop an ovary, but the Modern Family star got rough during their pseudo-lesbian kissing scene by tugging on her ponytail.
"That was her idea," Witherspoon told E! at the movie's premiere last night at the TCL Chinese Theatre in Hollywood. "It was not in the script. She just started pulling my hair and for the first couple of takes, I was like, 'Oh my gosh! This really hurts!' And then I was like, 'This is really funny!' So it was great!"??
