'The Voice': Kaley Cuoco's Sister, Briana, Tries To Turn A Chair (VIDEO)

So just what was Kaley Cuoco doing on "The Voice"? Don't worry, the "Big Bang Theory" star wasn't looking to kickstart a second career path. She was in the holding room being a supportive sister. Kaley convinced her sister, 24-year-old Briana, to audition. Briana had been working as Kaley's assistant, but her older sister convinced her to pursue her own dreams.

It's hard to say who was more excited when first Christina Aguilera, and then Ceelo Green pushed their buttons for her. Briana's beaming big sister was in tears backstage, jumping up and down in joy. In the end, Briana's journey will continue as a member of Team Christina.

But Buddy TV's Esther Gim had a mixed response to Briana's voice. "The music is overpowering her somewhat soft voice, but then she hits the bigger notes, and it's like the power came out of nowhere," she wrote. "Kaley's cute backstage during the performance as she's happy/crying for her sister ... It's funny that no one recognizes her last name, but I suppose it could've been edited out.”

Zap2It's Billy Nilles can't wait to see what's next for Briana. He said that it can't be easy being the younger sister to a star on TV's biggest comedy, but making a name for herself on "The Voice" should at least make it a little easier.

The journey continues on "The Voice," Mondays and Tuesdays at 8 p.m. ET on NBC.
