There's no use crying over spilled milk, but as for a bike ride? Well, that's a different story — just ask Justin Bieber and Hailey Baldwin.

The engaged couple turned heads earlier this week when — in the middle of a leisurely New York City bike ride — they were suddenly photographed bawling their eyes out while perched at a stop. It all seemed a little strange, but Bieber gave a hint to TMZ as to what caused him and his wife-to-be to break down.

"You got good days, you got bad days," Bieber told a TMZ reporter as he held up a copy of The Meaning of Marriage by Timothy Keller, a pastor and Christian apologist. His book notes that "Marriage provides the personal growth that comes through cross-gender relationships," and while he is a proponent of contraception, he is against abortion.

Still, tears aside, Baldwin and Bieber seem to be good for now, and have their sights set on the future.

Baldwin's aunt Kim Basinger told Us Weekly in July all about what the wedding might look like.

"Oh, it'll be fun. [Hailey’s sister] Alaia [Baldwin] and [cousin] Ireland, they're in the wedding. So believe me, I just — it's cool!" she said. "I think it's sweet. It's a very sweet thing. Happiness ... We're living in some really dire times right now."

She also addressed the couple's incredibly quick engagement by noting: "I'm very, very happy for Hailey. I think it's a good thing. I think Justin’s a cool guy. I don't really know him at all, but Ireland does, you know? I think he's come through a rough road. He's a really cool kid. I pray for them. I hope they're cool. I hope they're happy! It's wild! I think it's wild!"
