Allie shared the same pic, with the caption, "My best friend, love of my life…YES, yes yes a million times over."
It's unknown when the pair officially started dating, however they were first spotted together in public in December 2016 on a skiing trip.
ICYMI: Steven was previously dating his Vampire Diaries co-star Candice King (Caroline), back in 2010.
Although that didn't last long, Steven then started dating model Olivia Pickren in 2014, but they ended things about two years later.
Congratulations to Steven and Allie!
