Erin Napier Shows Off Husband Ben's Physique With Sweaty Gym Pic

Erin and Ben Napier

Erin Napier celebrated her husband Ben's 40th birthday with a glowing open letter and two intimate photos of the Home Town star.

The HGTV TV personality, 38, dedicated an Instagram post to her husband over the weekend that featured one family snap of Ben posing with Erin's father, Phil, as the two held a joint birthday cake and a second–a selfie–featuring just her shirtless husband post-workout.

"Lordy lordy, Big Ben is 40!" she began in the caption, going on to reveal that not only was Ben celebrating a big birthday, but so was her father, who appeared to be celebrating his 70th per the birthday wishes written in icing on the cake. "He and my daddy both had milestone birthdays this week!"

Erin continued gushing over her husband, writing, "I want to be like you, @scotsman.co: never looking back or feeling sad about our youth getting further away, but always feeling so grateful for right now."

"You’ve worked so hard this year to rehab your shoulder and transformed yourself in the process," she said of Ben's rotator cuff surgery, which he underwent this past spring before documenting his recovery journey online.

"The girls and I are so thankful for you," she added, "Here’s to 50 more birthdays together. I love you!"

It wouldn't have been a proper interaction between the pair had Ben not later replied in the comments, "Hey, eyes up. 😏," a phrase that's to be expected of him in response to his wife of 15 years' flirty jokes.

Among those wishing the home reno pro a happy birthday were metalworker and Fixer Upper regular Jimmy Don Holmes, who wrote, "Happy birthday buddy," and Hack My Home's Mikel Welch, "Happy Birthday!🍾🎂."

Erin and Ben have been married since 2008 and share two young daughters, Helen, 5, and Mae, 1.
