Kaley Cuoco isn't just dating tennis player Ryan Sweeting ... they're engaged! After a whirlwind three-month courtship, they're ready to commit for life!
Her rep confirmed The Big Bang Theory star's engagement Thursday.
"It's only been three months but she knows Ryan is the one," a source close to the 27-year-old actress explains. "When you know, you just know."
"[She's] never felt this way ... she knows this is it. And the ring is gorgeous!"
He proposed Wednesday, just a few days after we learned Kaley was dating Ryan Sweeting, 26, when they made their red carpet debut at the Emmys.
