As Life & Style exclusively revealed last week, Ashton Kutcher and Mila Kunis are currently expecting a baby boy, who will soon join big sister Wyatt, 2.
But the duo is at odds over whether or not this little guy will be their last bundle of joy.
"Ashton has always wanted three or four kids, but Mila only wants two," an insider tells Life & Style. "Now that she'll have one of each gender, Mila feels she can be done having babies."
Despite Ashton's desire for a bigger brood, he's looking forward to having a special "father-son bond" with this one.
"Even though they told everyone that they'd be happy with another girl, a son is what they were hoping for," the insider shares.
