Kaley Cuoco Ryan Sweeting Tennis star Barney's New York Beverly Hills

Make that Kaley Cuoco Sweeting -- girlfriend has already changed her Twitter handle to her married name!

On Friday Kaley and her hubby Ryan Sweeting went shopping at Barneys New York in Beverly Hills, and we're not sure when the lovebirds are going on a honeymoon, but they were indulging in some retail therapy in the meantime.

The duo tied the knot on New Year's Eve at Hummingbird Nest Ranch in Malibu, and the event doubled as a fire and ice themed holiday bash. Cuoco and Sweeting exchanged vows in front of 150 guests around midnight, and the Big Bang Theory actress wore a pink Vera Wang gown. The newlyweds posted a handful of photos on Instagram, and in one Sweeting wrote that his "cheeks hurt from smiling so hard" and that it was the "best night in history." Awww!
