Mark Wahlberg claims his mother tries to rule her family ''with an iron fist''.

'The Gambler' actor stars alongside his parent, Alma, and his brothers Donnie and Paul in new reality show 'Wahlburgers', and says they all make for an interesting dynamic on camera.

He explained: ''My mother tries to rule with an iron fist. We're all supportive of one another, yet competitive. We all bust each other's chops, but if anybody else tries to, you'll be ganged up on by all of us.''

Mark was one of nine children, but says he and wife Rhea Dunham are happy to stop after the four they have: Michael, seven, Brendan, five, Ella, 10, and Grace, four.

He added to People magazine: ''I didn't necessarily want to have nine kids like my mom had, but I certainly wanted a couple of boys and a couple of girls. I think we're at the perfect balance right now.''
