Kaley Cuoco has been a faithful fan of sister Briana Cuoco since she made it onto Christina Aguilera’s team on The Voice, and last night you could see her pain when Xtina chose Jacquie Lee as the winner of the battle round duet.

But the famous sibling, who had tears in her eyes during Christina’s critique, didn’t have to feel sad for long. Not only did Cee Lo Green enlist the recently introduced “steal” option, but so did country coach Blake Shelton.

Kaley, who was looking ultra-stylish in a grey fedora (take that, Justin Timberlake), nearly collapsed in relief knowing that her sister would live to see another day on the hit NBC show.

The Big Bang Theory actress took to Twitter to show her support before the show, writing, “A brunette Cuoco sister is about to #killit on #thevoice ! Don't miss it!!!!!!” Kaley’s fiancé, Ryan Sweeting, got in on the act, too, tweeting, “@bricuoco about to dominate on @TheVoice_TF1 tonight.”

Cee Lo told Briana there was a story in her voice, while Blake said the way she sings makes it obvious that she’s also a songwriter. Adam Levine, who was pulling for Cee Lo, warned Briana to avert her gaze, as Blake’s signature dimples have hypnotic power. In the end, the rocker with the gritty tone and old soul went with Team Blake.

Backstage, Briana, who used to be Kaley’s personal assistant, told her sister, “He's won three times in a row, so maybe this will be another one!”

You can’t fault the talented singer for using that line of thinking (although the dimples sure are adorable!).

What did you think of Briana’s performance during the battle? Should Christina have chosen her? Are you glad she went with Team Blake? Tell us your thoughts below!
