Kaley Cuoco was photographed Sunday without her wedding ring just days after announcing her divorce with Ryan Sweeting, the Daily Mail reported. “The Big Bang Theory” star’s representative told People magazine Friday that Cuoco and Sweeting “have mutually decided” to end their 21 months of marriage.

According to reports, Cuoco is moving forward with her life after splitting from her estranged husband. The 29-year-old reportedly enjoyed time with her dog Ruby in Thousand Oaks, California, Sunday. Cuoco was also spotted getting back to her old hobby -- horse riding -- during a competition at Flintridge Riding Club in La Cañada Flintridge, California, Saturday.

“She was extremely focused during the event,” a source told Radar Online. “You could tell that she was really enjoying being a part of the horse classic.”

Radar Online also reported that Cuoco was spotted hiding her ring finger a day before she announced the divorce. She reportedly hid her hands under the sleeves of her blue sweater.

The last time Cuoco showed off her 2.5 carat diamond ring was in August when she defended her husband after he was surrounded by cheating rumors.

“I have never been more proud of anyone on this planet -- this guy is fighting back from a whirlwind of injuries and not to mention constant ‘conversation’ regarding our marriage and basically any daily decision we decide to make,” Cuoco reportedly said at the time.

Meanwhile, another source told People magazine that the former couple tried to work out their marriage.

“The few times Kaley and Ryan were out together recently, the tension was noticeable. ... You could tell the honeymoon phase had ended,” the source reportedly said. “It seemed they were trying to work out their marriage by going on dates, but they both seemed miserable.”

According to reports, Cuoco has erased all signs of Sweeting from her Facebook and Instagram accounts, and also unfollowed the 28-year-old on the photo-sharing site.

Cuoco and the professional tennis player got married in December 2013 after getting engaged in September of the same year. The couple had dated for three months before their engagement.
