Everyone protect your ovaries: Josh Duhamel's 9-month-old Axl is dangerously adorable.

The 41-year-old star took to Instagram on Father's Day, June 15, to share a photo of his son with an appreciative caption:

"Proud to be this kid's dad," Duhamel wrote. "Happy Father's Day to all the dads out there."

Duhamel and wife Fergie welcomed Axl Jack Duhamel to the world this past August, and the actor has expressed plans to invest in his parental role:

"I'm excited and terrified, because I am responsible for this little thing. Forever," Duhamel told Jay Leno last year. To E! News, he confessed:

"It's very important to me that we raise this kid right."
