Dustin Johnson appeared to spill the tea about what goes on behind closed doors.

When speaking to the media Wednesday ahead of the 2023 PGA Championship at Oak Hill, the LIV Golf star was asked to elaborate on a prior back injury, to which Johnson responded with apparent details of his private life with wife Paulina Gretzky.

“I pulled a muscle in my lower back,” the 38-year-old Johnson told the reporter.

The former Masters champion then denied that the injury was due to “swinging a club.”

“Lifting up a kid?” a reporter asked.

“Yeah, lifting up a kid, a bigger kid,” Johnson said with a smile.

The press then burst out laughing as Johnson continued to grin at the podium.

Johnson’s media session came hours after Gretzky, the daughter of hockey legend Wayne Gretzky, gave fans an intimate look at the couple’s “late night” activities — golf practice.

“Late night lessons from hubby,” the 34-year-old Gretzky wrote Tuesday on her Instagram Stories.

Johnson and Gretzky got engaged in 2013 and tied the knot last spring.

The longtime couple, parents to sons Tatum, 8, and River, 5, swapped vows in a lavish outdoor ceremony in Tennessee.

Johnson and Gretzky celebrated their first wedding anniversary in April, the same month his 4Aces GC team finished first at LIV Golf’s tournament in Australia.

Johnson, who defected to the rebel golf tour last summer, nabbed his first individual win of the 2023 season this past weekend in Tulsa, Okla.

In his first year with LIV, Johnson earned more than $35 million in winnings.

Johnson is seeking his third major win at this weekend’s PGA Championship.

He finished second in 2019 and tied for second the following year.
