The 20-year-old actor, who plays Jacob Black in the "Twilight Saga" movies, took Mackenzie, 12, under his wing when she joined the cast of the last film as Renesmee Cullen and the pair bonded over sport, reported People magazine.
"Taylor taught me to play football, kind of. I wasn't very good at it," Mackenzie said.
The young actress also said that she and Nikki Reed, who plays her on-screen aunt Rosalie Cullen, had 'American Idol' night together.
The youngster was thrilled when she first heard she had landed the role of Edward Cullen and Bella Swan's half-vampire daughter and she and her mother celebrated together.
"I had just finished schoolwork. Then I got the phone call and I was like, 'Are you serious?' I was super happy. My mom and I celebrated with bananas and graham crackers. It was fun wearing a wig on set because I got to have super long hair. I always wanted long hair," she said.
