To get it, the NFL legend and perennial hottie (this haircut notwithstanding) says he's not above toddler-like tactics to get her to focus.
"I like attention from her, so when I'm not getting it I let her know in immature ways, like a young, immature child would," Brady, 37, tells Man of the World magazine for its fall cover story.
"You throw fits and you pout and you whine until you get what you want," he jokes.
Trouble is, he says, after five years of marriage, the Brazilian native, 34, has become wise to his moves.
"She's on to me, she knows all of my tricks," he says. "So now I have to learn new tricks."
With the facade of the gorgeous couple's perfect marriage fading quickly, the New England Patriots quarterback also says Bündchen has her imperfections, too.
Apparently, she's a nag.
"I'm a guy, what doesn't she get on me for?" he says. "That's just what wives do."
However, Brady, who has two kids with Bündchen – son Benjamin, 4½, and daughter Vivian, 21 months – hints that at the end of the day, she's the brains and he's the brawn.
"My wife speaks five languages," he says. "I always tell her I speak two: English and football."
