Kaley Cuoco’s Lookalike Sister Just Made a Surprise Appearance on ‘The Flight Attendant’

If the character Cecilia on The Flight Attendant looks familiar, it’s probably because she’s related to the show’s star, Kaley Cuoco (Cassie), in real life.

The actress in question is Briana Cuoco (AKA Kaley’s lookalike sister). Kaley celebrated the surprise cameo on her Instagram Story, where she shared a video of Bri’s scene (screenshot below).

ICYMI: Briana appeared in episodes four and five of The Flight Attendant, where she plays Cecilia (an assistant who’s obsessed with organization). However, her helicopter personality isn’t always a good thing. For example, Cecilia is known for eavesdropping on phone calls that are deemed confidential, which can only mean one thing: trouble.

The Flight Attendant (which is based on the best-selling novel by Chris Bohjalian) premiered on HBO Max in late November. It follows a flight attendant named Cassandra, or “Cassie,” whose life is turned upside down when she wakes up next to a dead body. With no memory of the night prior, Cassie is forced to follow clues in an attempt to figure out what happened.

In addition to the Cuoco sisters, the series also stars Michiel Huisman (Alex), Colin Woodell (Buckley), Michelle Gomez (Miranda) Zosia Mamet (Annie), Merle Dandridge (Kim), T. R. Knight (Davey) and Griffin Matthews (Shane).

Similar to Kaley, Briana has done her fair share of acting. (She even made a guest appearance on The Big Bang Theory back in 2013.) She’s also a talented singer/songwriter—not only does she sing for The Bluebird Band, but she also appeared on season five of The Voice.

Talk about a fantastic gene pool.
