The Big Bang Theory star, 27, posted a picture of herself to Instagram Sunday night, showing off her engagement ring and a hot-pink tank adorned with sparkles that spell out the word "Bride."
"Can't contain my joy," read the caption.
Cuoco recently said "yes" to tennis player Ryan Sweeting, and coincidentally, she's also playing a bride in the movie The Wedding Ringer, which started filming in Los Angeles in September.
Fans shouldn't have any trouble picturing Cuoco on her big day, as the actress has been posting photos of herself on set in a wedding dress with costars Kevin Hart and Josh Gad.
The actress also shared a snapshot of herself in the strapless lace wedding gown alongside Sweeting. The pair wear nervous expressions and Cuoco jokes: "Look who visited me on set of #theweddingringer! I think he's auditioning me. Hope I pass."
The happy couple attended a polo match over the weekend, where they enjoyed the "Polo tradition fixing the divots! #classy #toomuchchampagne #veuve," Cuoco wrote.
