WATCH: The 1975 'started to really care about' Ariana Grande and cover 'thank u, next'

The 1975 performed in the BBC Radio 1 Live Lounge promoting their new album A Brief Inquiry Into Online Relationships out Friday. They performed their new singles 'It's Not Living (If It's Not With You)' and 'TOOTIMETOOTIMETOOTIME'. The band also covered Ariana Grande's smash song 'thank u, next'.

Lead singer Matt Healy introduced the song saying, Ariana Grande has "become the main protagonist—is that the right word?—in most people’s lives. The person I see spoken about most. And somebody I’ve started to really care about for some reason. She’s had a right old tough time and I like her a lot. I think she’s cool. And she’s got a great voice. And I don’t. So I’m gonna sing one of her songs.”

Ariana Grande gave the cover her seal of approval with a black heart, and the lead singer returned the love on Twitter which, in keeping with their album title, started a brief online relationship.

The 1975 spoke on behalf of us all showing his appreciation for the artist, "We (and I mean society as a whole) fucking love you."

One tweet wasn't enough for Healy as he posted this sweetener.
