Kaley Cuoco's sister is getting married!

The Big Bang Theory star, 37, shared the happy news on Instagram Wednesday, revealing that her younger — and only — sibling, Briana Cuoco, got engaged to Brian Logan Dales.

"Engagement of the year!! 🩷🩷🩷 we love you @bricuoco @brianlogandales !! Fam for life! 💫 congratulations!!!!!!!" Kaley wrote.

Her post included several photos shot by photographer Jesse DeFlorio of the proposal, which took place outside in a garden filled with flowers, candles and twinkle lights. The special moment also included the couple's rescue dog, Joni, who was adorably accessorized with a bandana that read, "My humans are getting married."

One of the pics captured Dales — who is lead vocalist for the band, The Summer Set — down on one knee while another showed the pair kissing after Briana, 34, said "yes."

“My sister and my parents, we all have just forever and ever wanted to be rocks and supports for each other," she told E! News at the time. "Kaley is that for me and I am that for her, and it was incredible having her there at truly one of the best moments of my life. My parents are just the best people on the planet and they're so happy for me."

They have even shared the screen together. Briana had a recurring role on her big sister's hit series, The Flight Attendant, playing Cecilia during its two-season run on Max. Kaley said it was a "dream" to work alongside her sibling and travel together to the series' far-flung filming locations.

“Having my sister around, because she’s my favorite person, has been a dream to be able to work with her. This season, her character went to Iceland, so we got to be in Iceland together, which was a dream,” she told Collider of Briana, who also worked on The Big Bang Theory and Harley Quinn, two of the actress' other hit TV series.
