"They trusted us to figure it out," Robertson recently told E! News. "We just got lucky and figured it out. It was by the grace of God we have chemistry in this movie. We hate each other!"
"I don't know how I got hired," Eastwood joked.
"No, we're just pals, buddies," Robertson added before Eastwood chimed in, "Yeah, brother-sister...That's awkward, [we] like shower together."
"Loves incest!" Robertson quipped without missing a beat. "We were in the South," Eastwood joked of filming.
"We were in the South. They welcome incest in the South," the actress said.
Speaking of chemistry, Eastwood also recently opened up to Nylon magazine about their steamy sex scenes in The Longest Ride. "Britt is a beautiful woman and she's really professional and awesome. I'm pretty comfortable with myself in that sort of scenario," he said.
