Kaley Cuoco, Horse

Instagram

Kaley Cuoco has introduced a new member of her family, a day after it was revealed she and husband Ryan Sweeting had broken up.

Her rep had said on Friday the 29-year-old Big Bang Theory star and the 28-year-old tennis pro "have mutually decided to end their marriage." They were married for less than two years and have no children together.

"Welcome to the family, Zaza," Cuoco wrote on Instagram on Saturday, alongside a photo of herself kissing a brown horse standing next to an unidentified woman.

Cuoco, an avid equestrian, has posted on her Instagram page pics of herself riding horses in the past.

On the day of the announcement of her and Sweeting's breakup, Cuoco shared a pic of another furry family member—her dog Ruby, one of their many pups.

"#Mood," she wrote, alongside a photo of Ruby laying on her back on a table near a glass of rosé wine.

Also on Saturday, Cuoco posted pics of herself, including one with Ruby, promoting her friend's new Mexican bag line, which "promotes young entrepreneurs in Mexico and fights human trafficking."
