Kaley Cuoco received a very special message from Johnny Galecki on her birthday last week.

Over two years after their CBS series, Big Bang Theory, came to an end, Galecki, 46, took to his Instagram page, where he honored Cuoco as she celebrated her 36th birthday.

"Happy belated 48th birthday to my / worldwide adored, Mooks. @kaleycuoco," Galecki wrote on December 1, joking that Cuoco was actually much older than she is.

Luckily, and unsurprisingly, Cuoco wasn't offended by the joke, but amused.

In response to Galecki's message, Cuoco shared a series of laughing while crying emojis. And, right away, fans of the actors, and their long-running sitcom were thrilled with the interaction.

"We love you," one person wrote.

Another pointed out that they were quite happy to see that Cuoco and Galecki were still in touch -- and still close friends.

"It’s good to see you guys are still BFF’s... at least you are aging backwards from last year when he said you were in your 80’s," the person noted.

Others flooded Cuoco with their own birthday wishes.

"Happy birthday!" one said.

"He does you so dirty on your bday," another person joked, giving a nod to Galecki's 2020 message to Cuoco, in which he suggested Cuoco was decades older.

Other people mentioned that Cuoco, who is newly single after splitting Karl Cook months ago, date Galecki.
