Lili Reinhart may play an occasional River Vixen on the CW's Riverdale, but on Sunday night (January 6), the 22-year-old wowed on her first Golden Globes red carpet in a sheer tulle dress that I'm convinced came straight out of Cheryl Blossom's closet.

Just look at this radiant Khyeli Couture red tulle gown:

And this smokey eye and these diamond earrings are truly fit for a Serpent Queen — or Dark Betty, depending on the day. The slicked-back hair, however, is signature Betty Cooper.

Reinhart walked the carpet solo and confident. It's honestly hard to believe that this is her first Golden Globes; she's got her red-carpet smolder on lock. Not to mention, she's perfected the moody eyebrow quirk.

Maybe Betty will take a few notes for prom. We love watching Jughead Jones sweat!
