Julia Roberts and Sally Field aren't afraid to get dirty ... with their words!
The "Steel Magnolias" costars competed against each other in a "Curse Off" on Monday's "Jimmy Kimmel Live."
"We are honored to have both Sally Field and Julia Roberts on the show tonight, and it's also an opportunity to find out which of these incredibly talented women has the foulest mouth. Cover your ears, America, because it's time for our first-ever Celebrity Curse-Off!" Kimmel said before the challenge began. "The rules are very simple: each of our contestants will have five seconds to come up with a curse. No repeats allowed...whoever can't come up with a word will lose this competition."
"Why am I in a curse-off with 'The Flying Nun?'" Roberts joked, recalling Field's 1960s sitcom. "We'll see who's the Flying Nun!" Sally replied.
But, the Nun turned out to be naughty!
Field started to seamlessly string cuss words together, while Roberts struggled to come up with phrases that should be censored for TV. At one point, Kimmel joked, "This is a massacre!"
