Big Bang Theory’s Kaley Cuoco Engaged!

After just three months of dating, Big Bang Theory star Kaley Cuoco is engaged to tennis star Ryan Sweeting.

Kaley was spotted arriving to the BBT set yesterday morning sporting a rock on her ring finger.  Sources close to Kaley confirmed the news to the major media outlets today, saying Kaley knows it's fast, but they "just know" that this is the real deal.

This will be the first marriage for both.  Kaley was dating Superman star Henry Cavill earlier this spring, but they called it quits after a short time together. 

Congrats to them!
