'Loaded' is taken from his long-awaited forthcoming solo LP 'Coup De Grace' - his first since 2013's 'Don't Forget Who You' Are' - and it was just by luck that 'Honeymoon' hitmaker Lana came on board for the song.
Speaking to Anne Mac on BBC Radio 1, Miles recalled: ''Last January, Jamie T was in Los Angeles doing a little gig and we'd planned to some writing together that we'd been saying we'd do for 10 years.
''As I walked in [to the gig], Lana Del Rey was there.''
The song, the only one on the album to feature Lana, is inspired by Miles' break up.
On how the track came around, he explained: ''We were like, 'This is mental'. So she came over and we finished writing 'Loaded' in that afternoon.
''There was a lot of tunes that were written in that time, but this one's stuck around.
''It's the perfect tune, I think. It's got it all for me.''
The 32-year-old musician previously opened up about his new record and teased that most of the songs are ''upbeat and sort of punky''.
He said: ''It was amazing, in the first week we did about three tunes just in my apartment.
''[They have] a lot of words, which I don't usually do - that was what Jamie T was sort of encouraging me on.''
Speaking about teaming up with Lana on the record - which is named after the finishing move of WWE wrestler Finn Balor - he said: ''We've written a lot of songs together. One of them is on this album, and it's f***ing great.''
Last year, Lana revealed she and Miles had formed a band together, but they later axed the supergroup.
She said: ''I've done so much with Miles. I think at first me and Miles and some of the guys in The Last Shadow Puppets were working on a side project and had our own band.
''This was December through March. I didn't have a world tour planned and they didn't have anything either cos Alex [Turner] is working on his stuff, but, after listening to the songs, I felt like the songs were probably for Miles' solo stuff.
''Him and [The Last Shadow Puppets bassist] Zach Dawes are working on that.''
When Miles isn't working on his solo material he joins Arctic Monkeys frontman Alex Turner in The Last Shadow Puppets.
From 'Happy' to 'Banana Pancakes', these are soaked in positivity.
