The truth comes out!

Justin Bieber and Hailey Baldwin have kept everyone guessing as to whether they've tied the knot for months now, but they just let their own secret slip during a visit to the Stratford Perth Museum in Ontario, Canada.

JB took his lady love to see the new exhibit dedicated to his music career, and introduced her as his "wife" to staff and fans! Not only that, but the supermodel signed a chalkboard guest book of sorts, and the museum's social media page confirmed that the two were indeed husband and wife.

"I ❤️you forever-Hailey B". We were so pleased to have such a warm and special guest visit the museum yesterday (along with her very special husband 😊)," they captioned a photo of the board with her signature.

TMZ reports that the pair got married the same day they acquired their marriage license in NYC last month, and the only people that were in attendance were a preacher and a witness. Worth noting? They got hitched without a prenup!

Apparently, The Biebs is so in love with the blonde beauty, he thinks they'll be together forever and so he doesn't feel the need to draw up legal documents to protect his $250 million fortune. For his sake, we hope he's right!

They're still planning on having a formal ceremony, though, so at least we have that to look forward to!
