Here is a short article from Star Pulse in which he talks about what happened when his son met The Rock.
On the set of his new movie "Pain and Gain," Mark Wahlberg's 3-year-old son punched his father's co-star Dwayne "The Rock" Johnson in the genitals.
During filming, Wahlberg asked Johnson to stop by his trailer so his children could meet the former wrestler. He didn't realize his son's painful penchant for greeting men would apply to the three year old's hero.
Wahlberg recalls, "They're in the trailer, he gives my one son a high five and then the next one he goes to give him a high five and my son... (punched him) right in the nuts. I'm like, 'What are you doing, dude?' And he (Johnson) looks at me like I made him do it or something. I thought he was gonna try to, like, pick me up and slam me."
The film centers on a group of bodybuilding criminals and is directed by Michael Bay.
