“When You Know, You Know” Big Bang Theory Star Is Engaged!

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

According to Us Weekly, Kaley's representative has confirmed the news that the pair are intending to tie the knot.

A source close to the actress stated: "It's only been three months but she knows Ryan is the one. When you know, you know."

According to reports, Sweeting proposed just a few days after the pair made their red carpet debut for the Emmys.

The star confirmed earlier this year that she was dating Superman actor Henry Cavill, but the pair split after a shot time together.

Kaley began dating Sweeting in June and the pair made their first appearance in August of this year.

Henry who?
