The 38-year-old actress turned reality star announced recently that she is pregnant with her fourth child just six months after welcoming baby number three.

But Dean tells Celebuzz that it isn't entirely his fault that they are already expanding their family and does not regret ignoring doctor's advice of waiting six weeks before they were intimate again.

"It's so funny how everyone blames the man," the 45-year-old actor said. "It's like, Oh my God, will you leave your wife alone?' But it takes two to tango. She wasn't putting up much of a fight. But I have big shoulders. I'll take it."

The couple, who will celebrate their six-year anniversary next month, are parents to Liam, five, Stella, three, and Hattie, six months.

Dean added that he's delighted he gets to work with his brood on their hit reality show.

"Tori and I love the fact that we get to work together," Dean shared. "We get to work with Liam and Stella; we get to stay together as a family. As long as people want to see us, we'll keep making the show."
