The chemistry between Johnny Galecki and his co-stars has always been strong on-camera and off. One of his first public relationships was with his “Roseanne” co-star, Sara Gilbert, in the 90s, according to Ranker. The couple’s characters on the show had a picture-perfect relationship, but in real life, sparks didn’t fly. Gilbert revealed on “The Talk” (via “Today”) that during her relationship with Galecki, she faced the truth about her sexuality and Galecki fully supported her. After his relationship with Gilbert ended, “The Big Bang Theory” actor dated a string of co-stars, from Laura Harris to Ari Graynor, per Ranker.
Despite dating fellow actors, Galecki’s dating life didn’t get wide attention until he started a romance with his co-star, Kaley Cuoco. “Lenny” lovers rejoiced when they discovered that Penny and Leonard’s love story may become a thing in real life. In 2008, the two actors began their romantic relationship after meeting on the set of the CBS show, per Us Weekly. While fans were loving the idea, their characters’ love story was a burden to the two actors. Cuoco told Vanity Fair, “He was very protective of what the fans would think, because we wanted them to want Leonard and Penny together so badly, that if they saw us together in real life, it could ruin the fantasy.”
