It's always nice to see friendly exes, don't you think?
Actress Kaley Cuoco-Sweeting took a moment to post an adorable black-and-white snapshot with her Big Bang Theory co-star and ex-boyfriend Johnny Galecki in honor of his birthday today, captioning the picture, "Happy happy birthday to my tv fiancé and buddy buds for 8 years @sanctionedjohnnygalecki."
The pair shared the small-screen and carred on an onscreen romance for quite some time, but were able to keep their offscreen relationship a secret from the public for years. Cuoco revealed in 2010, while Leonard and Penny were on the outs, that she and Galecki had dated on the down-low for two years.
"We dated for almost two years. It was such a huge part of my life and no one knew about it," Cuoco revealed to a magazine back in September 2010. "This is the first time I've ever talked about it, ever. It was a wonderful relationship, but we never spoke a word about it and never went anywhere together."
"We're dear friends, still. Kaley's not just an ex, she's a part of my life," Galecki explained in the December 2013 issue of CBS Watch! magazine. "I just don't like to speak about it. And not because I'm trying to be enigmatic; I just worry that it will conflict with people's acceptance of Leonard and Penny."
Despite their real-life romance dissolving, these two have obviously remained dear friends, and when news broke that Kaley was going to marry tennis pro Ryan Sweeting after only a few months of dating, Galecki told E! News, "She's very happy, which makes me terribly happy."
