Dustin Johnson has already started teaching 3-year-old son Tatum how to perfect his swing, even if that means angering fiancee Paulina Gretzky in the process.

In an interview with Charles Curtis of For The Win, Johnson revealed he and Tatum often practice inside - something Gretzky isn't a fan of.

"I take him out in the yard and we hit balls, and we hit balls in the house and break stuff," he said.

Johnson said he "make(s) sure" Gretzky isn't around when they're practicing, but often gets in trouble once she gets home.

"I get yelled at," Johnson admitted.

Johnson and Gretzky have been engaged since 2013 and have another son, 10-month-old River, together. Asked about their wedding plans, Johnson said they haven't settled on anything yet.

"We're going to for sure, we don't have a set date yet, but we're in the planning process."
