Of many fans replying to the post. one of them was Jim Parsons, as a cute conversation between the co stars made their fans' day. Parsons commented, "We're still a pretty cute people, no? Too soon??? Love you" with a love emoji."

Bialik replied back saying, "Of course. Love you too. See you soon."

" yall are so cute✨" noted an Instagram follower, as another thanked the actors for raising awareness about censorship of women's faces in media. "We love you both tons!!! And thank you for raising awareness for such important matter," replied a fan.

I literally had no idea this proposal from Sheldon was coming. If you want me to tell you what happens in the season opener of season 11... I can't, because I don't know!

"I have opinions and ideas. As an actor and a writer, I could see this playing out several ways. But my job is to wait through the summer to see what our writers decide!" she added.
