The actress said that Vaughn's height created constant problems and jokes for the cast and producers of the festive film.
"He's 6'5" and I'm 5'2"," she told WENN. "We had a really funny scene, I don't know if it's in the film anymore, where he rolls over on to me.
"We were in bed and then at the very end he rolls over and goes to sleep, but he rolls over and lays on top of me. It was like a tree trunk had just landed on me. I kept going, 'Tim-berrrrr!" It was really funny."
She continued: "I stood on a lot of boxes and they had to build ramps that were about the same size as where I should be.
"It was a challenge, especially the kissing scenes... And he had to pick me up for half the dancing. He's actually holding me in the air so we can stay in the same frame."
