The actor - who plays Jacob Black in the 'Twlight Saga' movies - took Mackenzie, 12, under his wing when she joined the cast of 'Breaking Dawn - Part 2' as Renesmee Cullen and the pair bonded over sport.
She said: ''Taylor taught me to play football, kind of. I wasn't very good at it.''
Mackenzie also revealed she and Nikki Reed - who plays her onscreen 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.
She told People magazine: ''I had just finished schoolwork and I flopped down on the bed like 'Ugh, done'. Then I got the phone call and I was like, 'Are you serious?' I was superhappy. My mom and I celebrated with bananas and graham crackers.
''It was fun wearing a wig on set because I got to have superlong hair. I always wanted long hair.''
