The two lovebirds tied the knot on New Year's Eve and Kaley posted the first pic of Mr. and Mrs. Sweeting on her Instagram page with the caption "Yep #thesweetings."
The bride wore a pale pink princess gown and had her hair tied back in a messy bun.
Kaley caused quite a stir back in October after she posted an Instagram pic of herself wearing a white lace bridal gown, but she assured fans that it was just for her upcoming movie The Wedding Ringer.
No details have surfaced about the ceremony just yet, but Kaley did say she thought it would be cool to ride in on a horse and have a cake shaped like her dog's faces.
Kaley and Ryan got engaged in September after only three months of dating. Hey, when you know, you know, right?
Congrats to Mr. and Mrs. Sweeting!
