Kaley Cuoco might not be the only superstar in the family for much longer now that her sister, Briana Cuoco, is auditioning for "The Voice."

Season 5 of NBC's singing competition premiered Monday, Sept. 23. In the episode, Carson Daly tells Briana she's been chosen to audition in front of judges Christina Aguilera, Adam Levine, Blake Shelton and Cee Lo Green.

"You are the personal assistant to your uber famous sister here," he said while visiting her at home with Kaley by her side.

"It's her time to shine," added Kaley. "She's deserved this her whole life."

Kaley's "Big Bang" co-stars are equally as excited for the younger Cuoco. Mayim Bialik gushed about her to "Access Hollywood" while at the Emmys, saying she has "a beautiful voice" and is "phenomenal." Jim Parsons said he likes to joke, "Oh so finally the world is going to see the really talented Cuoco!"

After her quick appearance on "The Voice," Briana took to Twitter to thank fans for their support and to talk about the stint.

She also got a shout-out from former "Seventh Heaven" star Beverley Mitchell.

Although she might not be as famous as her sister, Briana has some experience working in the spotlight. According to her IMDb profile, she has appeared in "The Newsroom," "The Lizzie Bennet Diaries" and "The Mentalist," as well as "The Big Bang Theory." Last year, she choreographed a "Big Bang Theory" flash mob dance to Carly Rae Jepsen's "Call Me Maybe," according to The Hollywood Reporter. A video of the surprise performance wound up going viral.
