'Big Bang Theory' Wedding Prompts 'Congratulations' From Fans on Social Media

(Spoiler alert: Please do not read on if you haven’t watched the Season 9 premiere of “The Big Bang Theory”)

Is it going to be happily ever after for Penny (Kaley Cuoco-Sweeting) and Leonard (Johnny Galecki) on the “Big Bang Theory?”

Sadly, even the smart physicists on the hit CBS sit-com don’t have a simple formula for a perfect marriage as the lovebirds got off to a bumpy start on the Season 9 premiere Monday.

Things were made decidedly trickier after Leonard confessed to kissing another woman, Mandy, on his North Sea expedition two years ago.

While the pair streamed their nuptials in a Las Vegas chapel online for their nerdy friends to watch, viewers took to Twitter to share their congratulations for the fictional newlyweds.
