Normally it’s just her smile that lights up Kat Graham (Bonnie Bennett), but not in a photo she posted today. The Vampire Diaries star is in Philly promoting her new “Wanna Say” video, and she’s positively glowing. 

“Don’t be afraid of the dark,” she tweeted. Topped with an orange snow hat, the triple threat is sporting a luminescent dress.

We’re not quite sure how it all works, but Kat makes quite the night light!
