Kaley Cuoco will from here on out be known as Kaley Cuoco Sweeting -- at least on Twitter. The "Big Bang Theory" took on her husband Ryan Sweeting's last name on the social media account, though she hasn't added "Sweeting" to her Facebook page.

Friend Ellen DeGeneres -- who already "married" the couple once -- seems to confirm the name change. "Congratulations @Ryansweeets and @KaleyCuoco! Or as we can now call them -- The Sweetings," she tweets.

Meanwhile, Cuoco shared a video look at her wedding day that was posted by her makeup artist Jamie Greenberg. It shows Cuoco's wedding day preparation with her hair and makeup, and then fast forwards to her actual ceremony as she shows off her custom pink Vera Wang dress while walking down the aisle. The TV star already posted a number of Instagram photos detailing the New Years nuptials.
