Dylan Minnette and Lydia Night are getting cozy for the summer!

The couple stepped out together (and posed for some adorably loved-up photos) for Knott’s Summer Nights, a nighttime party complete with live music, food, and games at Knott’s Berry Farm in Buena Park, Calif.

The 22-year-old 13 Reasons Why actor and 18-year-old musician have been dating since last fall.

Dylan recently reconnected with his 13 Reasons Why co-star, Katherine Langford, who turned out to support Dylan’s band, Wallows.

“So proud of @dylanminnette ✨ you’ve been a rockstar since the day I met you, and @wallowsmusic absolutely crushed it last night! 🎸@braedenlemasters @colepressston ⚡️,” Katherine wrote on Instagram after the show, along with selfies with Dylan and a pic with his bandmates, Braeden Lemasters and Cole Preston.
