"This has been such a crazy year with so many challenges. This holiday season, it is more important than ever to spread love and kindness to everyone! Shawn and I wanted to send all our love to you amazing humans so we put together something special for you, our rendition of #TheChristmasSong," she wrote on Instagram. "❤️All streams will support those in need right now, and to kick this off, we are donating $100K to Feeding America! We love you all so much and hope you get to enjoy this song over a very safe and merry holiday! It would make our holidays if you went on their website and donated to one of their sectors and help out your community! They have sectors all over the nation. Let’s make our little corner of the world more beautiful today ❤️ Tarzan says hi."

In a couple of interviews this week, Mendes mentioned how happy he and Cabello are as a couple—and even said they have talked about getting engaged.

"Is she your forever person? Do you talk about an engagement one day?," Entertainment Tonight's Katie Krause asked Mendes.

"Yeah, absolutely, I think for me it's always been if I'm not willing to talk about that stuff then I kind of check out a little bit, and I don't know, I really think when you know, you know," he said. "She's been one of my best friends since I was, like, 15 years old. I don't know, at the same time, I know we're really young so I don't want to jump, like, insanely fast, but I think when you find your person, you feel and you know that you have found your person."
