"I'm the youngest of nine," the Lovely Bones star points out during a Friday appearance on The Ellen DeGeneres Show. "So the more the merrier."
Of course wife Rhea Durham – who delivered the couple's fourth child, daughter Grace Margaret, earlier this week – has a well-earned say-so in the matter, and for now she is standing pat. "My wife has always wanted four, two boys and two girls, so miraculously she got everything she wanted," Wahlberg, 38, explains. "She's saying she's done."
That's not to say a change of heart couldn't occur, however. Although Durham has been "hinting" that their family – which includes Ella, 6, Michael, 3 ½, and Brendan, 16 months – is complete, Wahlberg isn't so easily convinced. "She loves being a mother, so she may end up wanting one more," he muses before adding, "We'll see what happens."
Just what could motivate the model, 31, to contemplate a fifth pregnancy? The rest and relaxation afforded by the maternity ward. "She likes hanging out at the hospital," Wahlberg jokes. "It was the first time we had a couple of days of peace and quiet, even though she had to go through the pain of giving birth."
Likening the experience to a hotel stay, Wahlberg pointed out that mom and dad even had their own televisions for viewing. "She didn't really want to go home," he said.
