United Kingdom, Oct. 25 -- Lily Allen insists the mysterious Madeline on her new album is a fictional character construct of numerous people.

The 40-year-old singer has just released West End Girl - her first album in seven years - following her split from 50-year-old Stranger Things actor David Harbour in February after four years of marriage.

The 14-track record - which is "a mixture of fact and fiction" - explores themes of cheating, gaslighting, open relationships and sex addiction.

On the tracks Tennis and Madeline, Lily names a woman named Madeline, whom she questions after spotting a text message appear from her on a partner's phone.

Now, the hitmaker insisted to The Sunday Times that Madeline is "a fictional character".
