"What a blessing seeing two smart persons happy together and sharing love and friendship. @therealjimparsonsboth of you spread harmony, light and happiness," a user wrote.

The 44-year-old star CBS star gushed about filming Young Sheldon. Parsons, who will be the executive producer and narrate the show, said at the 2017 Television Critics Association press tour, "It was a moving experience for me to see something I've put a decade of my life toward [come to this]."

Parsons also spoke highly of Armitage during the panel. He said, "We have a lot more in common now than I would have had at the same age. I wasn't mature enough at 9. I was not an overly bright child. I was mediocre. I didn't befuddle my parents. That came much later, with my sexuality. Iain is much more in control as a human being than I was."
