Kaley Cuoco Talks Engagement while Sister Briana Auditions on

Her whirlwind engagement caught everyone off guard, but on Monday (September 30) Kaley Cuoco finally opened up about her blossoming romance with tennis stud, Ryan Sweeting.

During an interview with Entertainment Tonight, the “Big Bang Theory” star gushed, “From day one I just knew immediately and it”s been magic,” adding, “We have all the same family friends, we grew up with the same people, we just never met. So I kind of feel that I”ve known him my whole life. I know that it seems a little crazy on paper, but it”s what works for us.”

Trying to throw off his soon-to-be wife, Ryan “started a little fight with me and threw me off,” Cuoco laughed. “I was like “Oh my God, things aren”t great.” [But] he surprised me at the end of the night…he popped the ring out. It was amazing.”

Speaking of amazing things, Kaley recently supported her younger sister (and personal assistant) Briana as she auditioned for a spot on NBC”s “The Voice.”

In the episode which aired tonight, the young Cuoco performed Lady Gaga”s “You and I” and managed to get both Cee Lo Green and Christina Aguilera to turn around in their chairs.
