The Big Bang Theory actress posted a romantic photo of the newlyweds sharing an intimate kiss.
"Yep :) #thesweetings @ryansweething," the beautiful bride wrote on her Instagram account.
The 28-year-old opted for a showstopping pink tulle Vera Wang gown for her big day while tennis star Ryan opted for a casual look in a black shirt.
The famous couple, who started dating just six months ago, tied the knot on New Year's Eve surrounded by around 150 guests at Hummingbird Nest Ranch in Santa Susana, California. Their nuptials had a fire and ice theme.
Despite getting engaged just three months after they got together, Kaley has said she feels like she's known Ryan all her life.
"From day one I just knew immediately and it's been magic," she said.
"We have all the same family friends. We grew up with the same people, we just never met. So I kind of feel that I've known him my whole life. I know that it seems a little crazy on paper, but it's what works for us."
Like her new husband, Kaley was once a nationally-ranked amateur tennis player, but she retired when she was 16. The sporty actress is now an avid equestrian and owns four horses.
Prior to meeting Ryan, she had a brief romance with Man of Steel's Henry Cavill, and she secretly dated her Big Bang Theory co-star Johnny Galecki for two years.
