The photo was clearly a hit among her fans as the post drew a flood of compliments from her 3.3 million followers. A user wrote," Awwweeee!!!! True love." Another called them the "best couple" and noted, "Best couple!!! You guys are lovely."

"Truly a perfect picture! Get that in a frame pronto, girl!" an Instagram user gushed, while another claimed, "When they get engaged I think Instagram will burst with heart emojis. Cutest couple ever."

"Precious moments...enjoy them Sweet Souls @normancook," a comment reads. The Big Bang Theory star met professional equestrian Cook at a horse show in 2016, and they have been in love ever since. She was previously married to tennis player Ryan Sweeting and got divorced in 2015, just after 15 months of marriage.

Previously, Cuoco opened up about her future with Cook and told People magazine, "I don't know what the path is going to take. But I'm very happy right now."

Cuoco and Cook bonded over their love for animals. "He's got a big bulldog and many horses and luckily, I found a guy who likes dogs as much as me.That'smy number one list — 'Must love dogs!'" the comedy star gushed.

"We ride together and we both have a significant amount of horses in separate ranches. So we keep that separate, but we've done horse shows together and we travel together and that has definitely been a big part of our relationship," she added of her romance with the 26-year-old rider.
