Actress Kaley Cuoco of 'The Big Bang Theory' and her fiance Ryan Sweeting rang in 2014 in the biggest and best way possible – by getting married. One could say that the couple started 2014 with a big bang.

The actress posted a photo on her Instagram feed to share the good news. In it, she is wearing a fluffy pink dress and planting a kiss on her new hubby, who is a tennis pro!

Adorbs, right?

The actress simply captioned the shot as follows: "Yep :) #thesweetings @ryansweething."

Prior to marrying, Cuoco, 28, and Sweeting, 26, had been dating for about six months and they got engaged in September, which was about three months into the romance. Despite the breakneck pacing of the relationship, a friend told PEOPLE that the romance just…works!

The insider said, "Ryan is such a good guy," says a Cuoco pal. "They make each other so happy." Clearly! Look at that kiss.

Cuoco herself has spoken about the magic and connection between herself and Sweeting. Sometimes, you just know. Prior to dating Sweeting, Cuoco briefly hooked up with actor Henry Cavill of 'Man of Steel' fame.

Congrats to Mr. & Mrs. Sweeting!
