It is Kaley Cuoco that was dating Johnny Galecki, NOT Penny dating Leonard!!!
One person who got to share the love was Cuoco’s ex-boyfriend and “Big Bang Theory” co-star Johnny Galecki, whom she secretly dated for two years. “It took a minute, a bit of awkwardness,” she admitted. “By the grace of God, we became best buddies and moved on in such an elegant way. [He’s] one of my closest friends. He was in the front row at my wedding, with a huge smile on his face.”
Very gossipy I know ^^! but as a huge fan of this series for 7 seasons so far, it is indeed a big surprise. Ha.
