According to People, the author, walking with a friend by her side, wore a black long sleeves workout top with cutouts on the side and leggings of the same colour. She completed the look with dark shades, a grey denim jacket tied around her waist and a blue bag.
The couple got married on Saturday with the blessings of close friends and family in Montecito.
A source told PEOPLE that Katherine is "still feeling emotional and overwhelmed by the weekend, in a good way."
"She loves saying 'husband,'" the source explained. "She can't believe how much her life has changed since meeting Chris."
The source added, "He was very clear with his intentions from the start and she has never felt so loved and safe. They both feel so blessed to have found each other."
The newlywed couple shared identical posts from their wedding on Instagram where they can be seen walking hand-in-hand in their wedding outfits.
