It's Big Bang official! On Thursday night's Big Bang Theory, Kaley Cuoco's opening credits finally included her new husband's name . As fans took notice via Twitter about the change, so did the happy couple themselves.

"Seriously giddy," Cuoco Sweeting, 28, wrote via Instagram. Alongside the caption, the actress posted a snapshot of her new credit during the live airing of the CBS show. "Kaley Cuoco-Sweeting" appeared on the television screen at the same time her ex-boyfriend Johnny Galecki was in the middle of a scene. (The costars secretly dated for two years when the series first started in 2007. Galecki, 38, plays Cuoco's love interest on the comedy.)

Her new hubby Ryan Sweeting, meanwhile, also shared the photo. "Mrs. Sweeting @normancook #oldballandchain," the 26-year-old pro tennis player gushed.

As previously reported, the couple tied the knot in a romantic New Year's Eve ceremony in Southern California. Shortly after the nuptials — and sharing pictures of her stunning pink Vera Wang gown! — Cuoco also changed her name via Twitter.

The newlyweds clearly can't get enough of each other. On Jan. 8, Cuoco thanked her new hubby at the People's Choice Awards. "This is the second best thing that's happened to me this year," she said while accepting the award for Favorite Comedic TV Actress for Big Bang. "The first was marrying you, baby. I love you."?
