Sitting down recently with ET Canada, the duo got into a debate over which city is better, L.A. or New York.

“Ashton always says L.A., but I say New York,” Witherspoon said.

“You flipped me. Oh, wow. This is now, it’s aggressive, ET Canada, it’s aggressive what’s happening here,” Kutcher joked. “This is an aggressive approach to interviews, Reese needs to eat. We’re supposed to have lunch, she hasn’t eaten yet. She’s getting a little punchy. Reese said Los Angeles, I said New York.”

“Never said that… I said Miami,” Witherspoon laughed.
