Kaley appeared to show off her newly reclaimed maiden name by snapping a photo of her place setting at the Longines Masters event on Friday night (02.10.15).
The 29-year-old beauty snapped a photo of the dinner table setting - which refers to her as Kaley Cuoco - on
Instagram and wrote: "And my weekend starts right now."
The sitcom star and husband Ryan, 28, called it quits on their marriage on September 25 after just 21 months of marriage.
The pair tied the knot on December 31, 2013, after dating for just six months.
Kaley allegedly ended her relationship with Ryan after he became "addicted to painkillers".
A source told Us Weekly magazine: "She supported him but she said he couldn't make the commitment to get sober."
The family friend also revealed Kaley is "devastated" their marriage didn't work and has now been "sworn off dating."
Ryan, who was arrested for driving under the influence [DUI] and possession of a drug with the intent to sell in 2006, was reportedly prescribed the painkillers after he underwent surgery on his back last year.
The insider has claimed Ryan promised to check into rehab in Boston but, by the the time he agreed, it was too late.
