Lily Allen's new album will detail the breakdown of her marriage

According to the Daily Mirror, she said during a News Roast podcast: "Weirdly, this album is quite insular. Mainly it's to do with me and my relationship with my children, the breakdown of my marriage, substance abuse etc."

And Lily joked about her new boyfriend Dan London: "If we got married, I'd be Lily London."

The star also revealed her songs will be "a commentary in terms of the state of the world" and blamed Simon Cowell for musicians being less vocal about their political beliefs than they used to be.

She explained: "It's quite difficult to deliver a political message without sounding really preachy and earnest, and have a catchy pop melody at the same time. I have done it, twice, on this record, so look forward to it.

"Simon Cowell is a lot to blame – I really mean that, it's not a joke.

Before that style or that obsession with fame came to fruition, you needed to play an instrument to be able to write your own songs.

"There's usually some kind of political movement that went alongside any music.

"I think the internet is a big part of it. When the internet essentially de-monetised music – not for record companies, just for artists – it limited people in terms of how they were able to express themselves.

"You can't really be singing about your political beliefs if you're doing gigs for arms dealers or oil barons."
