Looking good, Kaley Cuoco!

The Big Bang Theory star turned heads at the InStyle and Warner Bros. Golden Globe after-party at the Hilton Hotel in Beverly Hills on Sunday night, sporting a super sexy red Christian Siriano dress.

The floor-length frock also featured a thigh-high slit, ensuring all eyes were on the beautiful blonde. Strappy sandals and an artfully messy bob completed her look.

Cuoco also got a chance to show off her new moth tattoo thanks to the dress' low-cut back. The 30-year-old actress got the ink in November to cover up a tat that marked her December 2013 wedding date to her ex, Ryan Sweeting, in roman numerals. Cuoco and Sweeting split in September after nearly two years of marriage.

"Note to self -- do not mark your body with any future wedding dates," Cuoco Instagrammed in November. "The deep, meaningful, larger than life meaning behind this beautiful piece of ink, is.... It covered the last one," she added.

Cuoco was also quite the social butterfly at the Golden Globes after-party, happily hanging with 51-year-old comedian David Spade.

Judging from Cuoco's sexy showing at the Globes, it's safe to say she hasn't been slacking when it comes to her healthy diet and exercise routine since her surprising split from Sweeting. Last month, she sent fans into a frenzy with a preview of her upcoming appearance on Spike's Lip Sync Battle, in which she sported nothing but a Calvin Klein bra top and ripped cutoffs.

And the admitted Bachelor super-fan has even more to smile about. ET recently caught up with season 20's main man, Ben Higgins, who personally invited Cuoco to Bachelor Live after she hilariously attempted to call in after the show's season premiere, but failed when didn't get through to the phone lines.
