On Monday night, Kaley, 33, and her sister, Briana, 30, had a sisters night out at the premiere of Netflix's "Between Two Ferns: The Movie" at the ArcLight Hollywood. While they have distinct differences in their appearances -- namely, their contrasting hair colors -- it is immediately clear upon looking at them side-by-side that they're sisters.

While Kaley is clearly the more famous of the two sisters, Briana is also a performer herself who has attended a slew of red carpet events with her older sibling. In addition to appearing on "The Big Bang Theory" back in 2013, she's also been in shows like "The Newsroom," The Lydia Bennett!!," "Criminal Minds" and "Mom." She was also on Christina Aguilera's "The Voice" team in 2013, where she lost in the Battle Rounds.

As for Kaley, in her post-"Big Bang" career, she has her sights set on doing more producing. First up is a single-camera comedy for, you guessed it, CBS.
