Johnny Galecki and Kaley Cuoco aren't just friendly costars, they're also friendly exes. On Saturday, The Big Bang Theory [3] actor was one of the many guests at Kaley and Karl Cook's wedding [4], and he made sure to congratulate the couple after the ceremony on Instagram. After posting a funny photo with the couple (where Kaley was cropped out), Johnny took a more serious note with his second post. "Couldn't be happier for my fake wife @normancook and @mrtankcook whose words brought us all to tears last night," he captioned a sweet black-and-white photo of him and Kaley holding hands. "So much love for you both."
While Johnny and Kaley's characters, Leonard and Penny, got married during season 10 [5], the two also had an offscreen romance. The costars dated for about two years [6] before breaking up in 2009. Despite their split, the pair have remained close friends [7], as evidence by Johnny's recent post. If you think these photos are adorable, be sure to check out all the photos from Kaley and Karl's nuptials [8].
