Let's GO,» Harris captioned the thirst trap, flexing his toned muscles in the mirror. Friends and fans responded in kind, dropping their well wishes in the comments and across their Instagram Stories. «What a stud,» Harris' longtime  co-star, Cobie Smulders, wrote. «Love you.» A post shared by Neil Patrick Harris (@nph)Earlier this year, Smulders and Harris reprised their  roles as Robin and Barney on in its freshman finale and season 2 premiere, respectively.

The Hulu spinoff stars Hilary Duff.«I was really nervous to work with NPH. He's just such a stud. He's legendary,» Duff told ET during set visit earlier this year.«Everything he does is, if he's hosting something or he's got a TV show on the air or he's doing Broadway, he's just fantastic.

And so the fact that he said yes made us really excited,» Duff added. «And obviously, our goal is to hopefully collect them all.»Harris also had cause for celebration last September as he and husband David Burtka marked eight years of marriage. «Eight years ago, our knot got tied,» he captioned a sweet photo of the two at the time. «He’s still the center of my world, the person I want to impress, the bright light in my life.»Harris is known to gush over Burtka any chance he gets.
