The Big Bang Theory star Kaley Cuoco grabbed attention in a stunningly sexy red Christian Siriano dress on Sunday night at the In Style and Warner Bros. Golden Globe after-party at the Beverly Hills Hilton.

The floor-length dress also had a thigh-high slit to draw attention to the stunning blonde. She finished her appearance with strappy shoes and a stylishly disheveled hairstyle. After a PDA-filled night at the People’s Choice Awards, Kaley Cuoco denies Johnny Galecki dating rumors.

The low-cut back of the garment provided Cuoco with an opportunity to display her new moth tattoo. The 30-year-old actress had the tattoo in November to cover up a tat with her ex, Ryan Sweeting’s, wedding date in Roman numerals for December 2013—almost two years of marriage ended in September with Cuoco and Sweeting divorcing.

At the Golden Globes after-party, Cuoco displayed excellent social skills and enthusiastically chatted with comic David Spade, 51. Since her unexpected breakup with Sweeting, Cuoco hasn’t been slacking off regarding her healthy diet and workout regimen, based on her seductive Globes performance. The teaser for her upcoming appearance on Spike’s Lip Sync Battle, in which she wore only a Calvin Klein bra top and ripped cutoffs, threw fans into a frenzy last month.

And there’s even more, to smile about for the self-described Bachelor superfan. He invited Cuoco to Bachelor Live after she unsuccessfully tried to call in following the program’s season premiere.
