It looks like a love match for Kaley Cuoco and tennis player Ryan Sweeting. A rep for "The Big Bang Theory" actress tells People.com the two are engaged. The couple attended the Emmy Awards on Sunday where Kaley's "Big Bang" co-star Jim Parsons picked up an Emmy for Outstanding Lead Actor in a Comedy Series. Cuoco and Sweeting just started dating this summer. Prior to Ryan, Kaley was linked briefly to "Man of Steel" star Henry Cavill.
