Lance Bass and his husband Michael Turchin are going to be dads!

After Bass shared a horror movie trailer TikTok hinting at the news Tuesday afternoon, PEOPLE can exclusively share that the artist, 34, and *NSYNC alum, 42 — who have been married since 2014 — are expecting their first children: boy-girl twins in November.

“It has been quite the journey,” Bass tells PEOPLE, referring to years of surrogacy attempts, failed IVF treatments and a miscarriage.

PEOPLE: Congratulations — so excited for you two! I know it’s been several years in the making — what’s it like to know you’re finally going to be dads?!

Lance: You have your vision of how it’s all going to go, right? When we went into IVF and surrogacy, we had no idea what it was all about. Pretty much everyone we’ve known had bad luck at the beginning. The first time they tried it, it just did not work. And I feel like that is such a common thing. And it’s great that we’re able to talk about this because a lot of times I would believe that couples feel very alone in that situation. But to know that other people are going through the same exact thing, it’s really comforting.
