Eyes are on Kaley Cuoco's little sister Briana right now. The 32-year-old sibling to "Big Bang Theory" alum Kaley is in the news anyway right now featuring on Kaley's new HBO Max series "The Flight Attendant," with Saturday bringing a beast mode workout as Bri updated her Instagram stories during a sweat session. Bri, who is a workout queen and also runs her Cult LA athleisurewear clothing line, showed the 'Gram how it's done, and she picked one killer look to do it in. Check it out below.

Scroll for the workout action, although if you follow Kaley on IG, you'll have spotted the summer shot as the siblings worked out in L.A. Bri, who joined Kaley for a two-month summer shooting stint in NYC and was spotted shopping at Alo Yoga while in Manhattan, was proving that she doesn't just shop the gym wear. This girl uses it.

Bri opened with a quick squatting selfie as she wore a tiny black spandex sports bra and leggings, but that was just the warm-up.

Bri's indoor workout, seeing her energetically busting out burpees and Switch Climbers with Plant Tucks, came just after 9 a.m., with the actress and "The Voice" alum seen on a mat and with Apple Air Pods as she burned those calories.

"I put on a song w a quick BPM n try to stick with it the entire block. Was listening to this em for dis one," Bri wrote, shouting out rap superstar Eminem as she played his "On Fire" track.

Bri was making headlines before "The Flight Attendant" premiered on November 26. The star, who featured on a 2013 episode of "Big Bang," appeared on Kaley's popular "A Cup of Cuoco" Instagram series this summer, with the two seen during their 14-day mandatory quarantine in upstate NY.

Bri also turned 32 just days before Kaley turned 35 this fall. "Happy birthday sissee!!! actually don’t know what i’d do without you. i love you so much & thank my lucky stars God gave me you to do life with ???‍?‍??" she captioned a candle birthday snap.

Bri's birthday post definitely brought in the Kaley fans, with remarks coming in over how similar the siblings look, even if one is blonde and one is brunette.

"So...silly question but are you 2 twins or just share a bday with each other? ? Happy Birthday ? either way!" one follower wrote.

Bri has also been reflecting on 2020, with a recent selfie shot seeing her joke that her "biggest takeaway" of the year was "how much she loves a photo carousel."

Meanwhile, Kaley's nightie bedtime binge just got exposed by her husband. Check that out below.
