Kaley Cuoco Makes A Big Bang At Sister's Candlelit Birthday

Scroll for the photo. If you aren't familiar with Bri, the Cult LA founder, who appeared on a 2013 episode of "Big Bang," is set to become a bigger deal thanks to "The Flight Attendant." Paparazzi snaps of Briana this summer exploded as she joined sister Kaley during the blonde's two-month shooting stint in NYC, with last night once again bringing the siblings together.

The photo showed Kaley and Bri cozying up at a restaurant table and with the two seen in front of a layered birthday cake with candles.

Bri, laughing and also hugging Kaley, had seemingly been treated to the best night out ever, with Kaley likely turning fan heads as she showcased a different hairdo – it's bangs for the girl behind Penny now.

"November birthday twins," Kaley wrote with cake, firework, and heart emoji, also shouting out Briana's IG handle. Earlier in the day, Kaley had posted a stunning backyard selfie with Bri, telling "The Voice" alum she's headed for great things. Scroll for more photos after the snap.

Kaley's shout-out was a loving one, with the California native writing: "HAPPY HAPPY BIRTHDAY TO MY FAVORITE SIDDER ON PLANET EARTH!!! You are so special to so many and I’m constantly in awe (and slightly jealous) of how cool you are ! 🎉🎀🎈🎁🎊 love you so much ..you are on the brink of greatness! @bricuoco."

Fans, who have been saying that "2 is better than one," have been filling the comments section. Some, with "BBT" jokes: "Knock knock Penny, Knock knock Penny, Knock knock Penny... what? This is a Birthday bread 🤔❤️," one wrote.

Bri has steadily seen her profile climb this summer. It all kicked off when she started featuring in episodes of Kaley's popular "A Cup of Cuoco" Instagram series. The impromptu videos seeing Kaley enjoy her first coffee of the day while sharing her random thoughts turned double trouble in August as the sisters underwent a mandatory, 14-day quarantine in upstate NY, with Bri then appearing in "A Cup of Cuoco" videos from the Big Apple as the two shot "The Flight Attendant."
