Willie Nelson can now add "model" to his resume. The 80-year-old joined his two sons, Lukas and Micah Nelson, to pose for a new line of clothes by designer John Varvatos.

"John Varvatos and his team are great -- his clothes look and feel good on your skin and are made for every man ... and his sons,” Nelson notes.

Lukas Nelson agrees. "It was a great pleasure to get to know John and hang with him,” he says. “We all seem to have a similar outlook on life and it was nice to have my whole family together in the same room for this shoot."

Adds Micah, "When you dress sharp in John Varvatos, it's easy to feel like the biggest gangster badass in the room. It was a special day."

The tender family photos had the full approval of Varvatos. "In all the iconic music ad campaigns we have shot over the last eight years, I have never been so moved as I was working with Willie Nelson and his sons," he notes. "Willie is a true American Icon and it runs deep in the bloodline. I am proud to be friends with Willie and his beautiful family."

The entire campaign was shot at the famed '20s Salisbury House museum in Des Moines, Iowa, which was the perfect backdrop for the singer to pose.

"We created a mini documentary featuring Willie and his sons playing guitar together and performing the song 'Still is Still Moving to Me,' cut with moments of the three talking music and style influences, growing up on the road, having famous 'uncles' (Johnny Cash, Kris Kristofferson, Waylon Jennings) and hating haircuts,” reveals Stephen Niedzweicki, founder and chief creative officer of YARD and longtime Varvatos collaborator.
