Lily Allen dropped a pretty strong hint that her marriage might finally be over as she appeared on a radio phone-in show, telling listeners during a discussion about education that she wants her children to learn about “divorce” and “the dangers of marriage”.

The 30 year old singer, whose marriage to Sam Cooper has been rumoured to be on the rocks for some time, told LBC presenter Shelagh Fogarty on Thursday morning (February 11th) that she’d replace maths and science on the curriculum with lessons about the benefits and drawbacks of getting married, as well as the more practical side of life.

Allen would introduce “a beginner’s guide to getting food” and “an introduction to divorce” as courses on the national curriculum. Prompted by these remarks, Fogarty decided to address the rumours of the singer’s disintegrating marriage. “Is there something you need to tell us, Lily?”

The Sheezus singer ducked the question, continuing: “It seems people get themselves into all sorts of situations and they have to spend extortionate amounts of money on accountants and lawyers to sort it out.”

Allen has been married to 37 year old Sam Cooper, a builder by profession, for four years, and they have two children together, Ethel (4) and Marnie (3). However, they’ve not been spotted together since last summer and Lily is believed to have moved into a new house, having effectively lived separate lives for some time.

Lily had become prominent in the debate about education, as two days before she had got into a heated argument with MP Nick Gibb, Minister of State for Schools, on Twitter about the usefulness of Pythagoras Theorem and Bunsen burners and why more practical life skills weren't being taught.

During the phone-in, Lily continued that being able to get your head around finances, rather than the pure art of maths, was more important to children. “I've never been able to get my head around my finances. I was terrible at maths. I've had an accountant in employment since the age of 19.”

“If my daughter came to me with any questions about any of this stuff (mortgages etc.), I would not have a clue. It's more me worrying about my children and them having to face the big, bad world without the necessary tools to do so.”
