The real-life relationships of The Big Bang Theory cast

begin >>

The Big Bang Theory first premiered on CBS September 24, 2007. The sitcom about a group of science geek friends was a hit from the very first episode, and it made nerds (and non-nerds alike) fall in love with the adorable personalities of the lead characters.

Geeks everywhere cheered when they saw that at last socially-awkward geniuses got the beautiful girl on television, instead of rejection. Throughout the last 10 seasons of The Big Bang Theory, many on-screen (and off-screen) relationships developed. One of the most famous being Leonard (an experimental physicist) and his blonde bombshell of a neighbor/aspiring actress Penny. When the two first met, it seemed like someone like Leonard, who was not nearly as tall, hunky or muscly as Penny’s previous boyfriends, would ever go for someone like him. In a delightful turn of events, the two form an incredible relationship (on and off) and eventually get married!


Of course, sometimes we have to remind ourselves that it is only a show- and that the cast have their own real-life relationships at home. (I know, sadly Bernadette and Howard do not really have a cute baby together and Sheldon and Amy are not really going to get married.) However, the actors and actresses real girlfriends, boyfriends, husbands and wives are also pretty amazing if we do say so ourselves- so why not give them a chance?

The cast of The Big Bang Theory are of course nothing like socially-awkward nerds in real life, and are actually highly successful and confident human beings (and millionaires.) So it is no wonder that they have dated some of the most beautiful people.
