Kaley Cuoco made her first red carpet appearance with her new boyfriend on Friday night (20.09.13).

'The Big Bang Theory' actress, who split from 'Man of Steel' star Henry Cavill in July, proved she is well and truly over the break-up by attending Entertainment Weekly magazine's pre-Emmys bash with her new beau Ryan Sweeting on her arm in West Hollywood, California.

The 27-year-old actress also tweeted a new picture of her with the professional tennis star, 26, from the event, with the caption: ''#emmyweekend greatest date ever ryansweething.''

Rumours first began swirling that the couple were dating in early August, just weeks after Kaley's fling with Henry ended.

A source previously said the blonde beauty was overwhelmed by all of the attention surrounding her relationship with the 30-year-old British actor.

The insider said: ''She just got overwhelmed with the very public Superman relationship. She's not used to that much attention and chaos in her life.''

Kaley briefly dated musician Bret Bollinger after ending her engagement to Josh Resnik in March 2012.

She also previously dated her 'Big Bang Theory' co-star Johnny Galecki for two years, but the pair managed to keep their relationship a secret for the duration.
