Kaley Cuoco is her sister Briana Cuoco's biggest supporter and vice versa!
So we know Kaley was watching last night as Briana did her best Gwen Stefani impression on The Voice!!!
Unfortunately she was up against one of the best singers on the show in Shelby Z. and the two had a ferocious singing battle!
It was SUPER close, but in the end there could only be one!
And unfortunately that one wasn't Briana! But even though she was booted off the show - we have a feeling we're going to be seeing a lot more of this talented star in the future!
Check out her deciding battle by watching the video (above) !!!
