Taye Diggs and his son could not be cuter, milk mustaches and all.

The hunky Private Practice star is currently featured in a new milk ad campaign with his real-life three-year-old son, Walker.

Walker's mom is Taye's wife Idina Menzel, a Broadway star who is known for playing Rachel's mom on Glee.

“Being able to shoot the Got Milk? ad with my son was one of the better times in life just because, obviously, the ad is going to last forever,” the 42-year-old dad tells People.

However, Walker needed a little encouragement to properly ham it up in front of the camera.

“We had to constantly make up games and excuses just to keep him occupied,” Taye admits. “So when it seems like he’s smiling, he’s actually roaring because he wanted to be a tiger.” What a coincidence  we want to be a tiger, too!

Regardless of how it came together, this ad campaign photo is ridiculously cute.
