Kaley Cuoco looked gorgeous in a oxblood Vera Wang gown last night -- but her best Emmy Awards accessory was on her arm.

No, not the bracelet ... her new man!

The "Big Bang Theory" star went public over the award show weekend with her new boyfriend Ryan Sweeting, who looked sexy in all black tux, dress shirt and tie.

Cuoco, 27, and Sweeting, 26, have been dating since early August -- right after Kaley had a quick summer romance with "Man of Steel" star Henry Cavill.

So, who is he?

Her hunky new beau is a Bahamian-born professional tennis player who has played in the US Open, Wimbledon and the Australian Open.

Kaley seems pretty happy with Ryan, tweeting a cute message while attending a pre-Emmy party together on Saturday night.  

Not too shabby, right? See more Emmy celeb sightings above!
