If you’re paying as much attention to Kaley Cuoco (and her Instagram feed) as we are these days, then you’ve probably noticed a recurring brunette in a variety of the 34-year-old’s posts.

Turns out, that’s The Big Bang Theory star’s younger sister, Briana (we probably could have guessed that considering they look almost identical aside from the hair). Naturally, we needed to find out all we could about the actress’s little sis. And from what we discovered, the 31-year-old has a pretty impressive resume of her own. Keep reading for everything we know about Kaley Cuoco’s sister, Briana Cuoco.

1. Who is Kaley Cuoco’s Sister, Briana Cuoco?

Briana is a singer/songwriter and part-time actress.

She entered the music industry and has made quite a name for herself as an artist. Not only did she appear on season five of The Voice (unfortunately, she didn't make it all the way to the end), but she’s also a singer for The Bluebird Band, which is now streaming on all music platforms, including YouTube, Spotify and Apple Music.

Aside from her original music, her covers (many of which are tied to her appearance on the competition show) have also gained a lot of attention online.

Like her older sister, Briana is also an actress. In fact, Kaley even landed her a guest spot on an episode of The Big Bang Theory back in 2013. Since then, she’s also had small roles on shows such as The Mentalist and The Newsroom. And according to The Blast, she's set to make more appearances in Kaley's upcoming HBO Max series The Flight Attendant.
