Kaley Cuoco and her little sister Briana decided to sunbathe in a row as they hit a NY beach this week – complete with the "Big Bang Theory" actress' assistant Emma Ross. Kaley, 34, has been making major headlines for a 14-day quarantine period in upstate New York as she and Bri geared up to finish filming upcoming HBO Max series "The Flight Attendant."

Kaley has been documenting the whole trip via Instagram. Likewise, 31-year-old Cult LA founder Bri, who today posted a giant summary of the trip. Check it out below.

Scroll for the beach action. If you aren't up-to-date, the girl behind Penny has her new HBO Max series back in production. The above photo comes from Kaley's "A Cup of Cuoco" Instagram series, with the latest episode seeing Kaley and Bri discuss quarantine essentials – seemingly, including a joking bourbon suggestion for morning vitamin C woes.

Bri updated her Instagram ahead of the weekend. She opened with Kaley driving and the two singing along to music. Fair warning, you'll have to swipe a fair amount for the beach, with the video also including river scenery and joint wine drinking.

The video, below, eventually showed Kaley, Bri, and Emma all on a beach and lounging back in deckchairs. Briana, who runs an athleisurewear line and will feature in "The Flight Attendant" was in selfie mode and flaunting her rock-hard body in a cute, cupped, and black bikini. The camera then swung over to briefly film a swimsuit-clad Kaley chilling with assistant Emma.

"First we did that quarantines then we did tha tings," Bri wrote.

The "quarantines" has gotten major coverage on Instagram. More after the video.

Kaley's New York trip has come complete with an Instagram account dedicated to chihuahua Dumptruck Dumpy's experience of the travels. @dumps_does_ny racked up over 46,000 followers in just a few days. The "foster fail" taken in by Kaley and billionaire heir husband Karl Cook back in March has gotten ice-cream, chopped chicken mortadella breakfasts, and a brave video of Kaley cleaning up after him on a New York sidewalk today.

Kaley may be the big face, but sister Bri, who has featured on "Glee" and in a 2013 episode of "Big Bang," is set to receive more exposure.

Kaley and Bri have been featuring in joint posts for years, with the sisters upping their joint presence as they quarantined in Kaley's $12 million Hidden Hills estate prior to jetting out to New York. On July 15, the sisters posed in a workout photo shouting out Bri's Cult LA label. As The Blast reported, fans weren't sold on the $186 leggings and $98 sports bras.

Bri defended the price tag, though, stating that the apparel is U.S. made. She also promised to widen size ranges once her company was no longer in tiny start-up mode.
