The pair also took a trip down to Niagara-on-the-Lake, where they visited some vineyards.
The 27-year-old supermodel and 29-year-old actor recently celebrated their two-year anniversary.
Palvin previously revealed how she met her boyfriend, telling W Magazine that he actually messaged her first.
“He slid into my DMs,” she told the mag.
He agreed: “She followed me, so I was like, I guess I’ll give her something. And I slid into her DMs. I was like, ‘Hey, I don’t know if you’re in New York for very long, but we should hang out if you want to. Here’s my number.’ And she didn’t message me for six months.”
