Actress Kaley Cuoco was thrilled to see her sister Briana sail past the blind auditions on TV talent show The Voice on Monday (30Sept13). Briana Cuoco, who has worked as her sister's personal assistant, impressed both Christina Aguilera and Cee Lo Green, who picked her for their teams. She ultimately joined Aguilera. Speaking to show host Carson Daly, The Big Bang Theory actress said, "I've been waiting for something like this for so long for her. She's deserved this her whole life. She's always put herself on the back burner for everyone else. This is her time now... I want this for her probably more than she wants it."
