Kaley's handsome leading man! Kaley Cuoco and her boyfriend Ryan Sweeting made their first official red carpet debut as a couple at a pre-Emmys bash on Friday, Sept. 20. The two kept close as they attended Entertainment Weekly's party at Fig & Olive Melrose Place in West Hollywood, Calif.

The fairly new couple matched for the big night, with the Big Bang Theory actress wearing a tight black Pamelle Roland dress and Pedro Garcia shoes. The tennis star wore a black suit with a skinny tie.

"#emmyweekend greatest date ever ryansweething," Cuoco, 27, tweeted about her new beau.

The blonde beauty and Sweeting, 26, first sparked rumors of a budding romance when they were spotted together in early August. On Aug. 2, the athlete joined Cuoco at a horse ranch in Moorpark, Calif. The following day the two grabbed lunch at Marmalade Cafe in Sherman Oaks.

As Us Weekly first exclusively reported, Cuoco moved on to Sweeting shortly after having a brief fling with Man of Steel hunk Henry Cavill in July. Cuoco's other exes include addiction specialist Josh "Lazie" Resnik (they called off their engagement in March 2012), and her Big Bang costar Johnny Galecki. The two actors kept their relationship tight-lipped for two years.
