But this interaction wasn’t the start of Chalamet’s interest in Liverpool.
The actor started to be linked to the city last year when speculation arose that he was masked Merseyside rapper EsDeeKid.
During a BBC interview to promote his film Marty Supreme, the actor declined to defuse the rumours or put on a Scouse accent.
Referencing the iconic Liverpool phrase “chicken and a can of coke”, he replied: “You want me to talk about ‘chicken and coke’ and stuff like that, right? No, you’ll see all in due time.”
A few days later, he shared a clip of him performing alongside the rapper at an off-licence and inside a kitchen.
Liverpool film-maker Archie Erskine, who took the train to London to make the video, told GQ magazine, external that Chalamet’s lyric “I got a can of Coke and that cheque in” was “making sure people understand how long Liverpool rap has waited for a moment like this and how long it has previously existed”.
“There are so many great artists people will now be exposed to.”
