It was really odd. I wrote it around the time I was actually getting back with someone. Deep-down, it felt weird. Like, why do I seem so much more into it than him? It wasn’t like that when it started! But I was still so in love [I was trying to ignore the signs], even though I knew it wasn’t it…I was just running through those red flags!

Looking back at it, though, you connect the dots. I was very in love, I think sometimes you want what you can’t have. It can be really challenging and you have to have such a discipline to walk away. For me, I look back at our old conversations and, honestly, that person was really trying to get me to get break up with them. I didn’t even see it! I thought it was all green flags.

I wrote this with Connor McDonough, Riley McDonough and their brother Toby McDonough and with CASTLE and Ryan Daly [Cirkut also helped produce and co-write the track]. We wrote it at the end of last summer. We did a lot of really sick songs that are on the album.

We were all just talking about red flags [while writing it], I think I was honestly just trying to get advice from them, you know. When you have a group of guys in the room, who better to ask? I’ve known these boys for years, literally when I was in LA signing my deal. It felt very full-circle.

“Red Flags” is such a fun, sassy song. It’s about realising someone’s not right for you, and they’re non-stop showing red flags, but you keep running through them because you’re so obsessed. You keep doing it, but you don’t care because that adrenaline rush and excitement is all part of it. It’s all over the shop, but I think it’s so relatable.
