The heartbreak that inspired Adele to pen her acclaimed music was inspired by an ex-boyfriend who left her for her gay friend, a new biography claims.
In Adele: The Biography, an unauthorized tome, author Marc Shapiro pays particular attention to the incident in which, allegedly, Adele was dumped.
He says it went down on Adele's 18th birthday and inspired her career.
"One thing we know is that it was a first love gone terribly bad," Shapiro writes.
"Adele had professed her love and he did the same, she had known he was bisexual but, in the rush of romance, felt they could make it work."
The book goes on to claim that "four hours after laying their emotional cards on the table, the boy ran off with one of Adele's gay friends!"
A 2011 article in Out magazine also said Adele wrote two songs, "Hometown Glory" and "Daydreamer," about a bisexual boy she had fallen in love with.
Both of the songs ended up on Adele's 2008 debut album, 19. The singer herself has offered few, if any details about the relationship.
