Lili Reinhart might be celebrating her birthday on Friday the 13th, but her boyfriend Cole Sprouse [1] feels incredibly lucky. In celebration of the Riverdale [2] star's 23rd birthday, Cole shared a cute message on social media alongside some PDA-filled snaps. "Lil @lilireinhart was born on a Friday the 13th and haven't I just been so lucky ever since?" he wrote alongside four photos, which show the couple cuddling up, kissing, and Cole pretending to bite Lili's neck.

The lovey-dovey post comes just a few days after Lili confirmed once and for all that the couple is back together [3]. Following their brief split this Summer [4], Lili set the rumours straight about the state of their relationship when she referred to Cole as her boyfriend in an interview with Coveteur. While discussing her Halloween [5] plans, the Hustlers actress said that she was thinking of doing a character costume this year. "I think I'm going to do it with my boyfriend, Cole. I don't want to spoil it if it's not going to happen, but it's a TV duo." Perhaps Cole and Lili are dressing up as fellow CW couple Damon and Elena from The Vampire Diaries, so they're practicing their biting now?
