The Twitter-happy star landed a place on the 2018 shortlist for her fourth album No Shame.
Chatting at the Langham Hotel shortly after wiping away tears from her eyes, Lily said: “I’m not sad I’m just happy.
“There wasn’t a big spend behind this album, it is what it is, it feels natural and organic.
“The nomination means a lot to my 21-year-old self, I thought these days were long gone.
“For me this award and Ivor Novellos are the big ones.”
Never one to hold back her true feelings, the mum-of-two added: “This isn’t the music industry, this is a part of it.
“Ask record labels, they don’t give a f*** I am here. This part has got lost.”
As well as recognition in the industry, the winner of the coveted Mercury Prize also bags a cheque for £25,000.
When asked what she would spend the cash on, the ever-political chart-topper replied:”I’d put it into my post Brexit account probably to pay for visa applications.”
In a shock swipe at her record label Parlophone, Lily laughed: “I want support from my label [if i win] and a video budget.”
Throughout No Shame, Lily sings about the breakdown of her marriage, being a working mum and substance abuse.
“It is just so frank that it is what it is,” Lily explained.
“The nomination means a lot to my 21-year-old self, I thought these days were long gone”
Piers Morgan’s arch nemesis added: “You don’t need to use your imagination, it is just there.
“I really, really struggled over the last few years and I tried to be as honest as I could.”
Explaining how she isn’t worried about making chart hits anymore, Lily said: “I initially went into the record without thinking about how it would be perceived.
“Actually it wasn’t about my fans, but how I was going to feel getting up on stage at night and singing it over and over again.
“It was really important to me that the songs were honest.”
Despite her ‘me first’ attitude, No Shame managed to break into the UK Top 10, peaking at no8 on the charts following its release.
Lily, and the rest of the UK, will find out the winner of the 2018 Mercury Prize Album of The Year award on September 20.
