"One thing we know is that it was a first love gone terribly bad," author Marc Shapiro writes in Adele: The Biography, according to excerpts posted on the U.K. Daily Mail. "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. Four hours after laying their emotional cards on the table, the boy ran off with one of Adele's gay friends!"
Adele herself sort of confirmed the claims in her official website biography.
"'Daydreamer' is about this boy I was in love with, like proper in love with, he was bi and I couldn’t deal with that. All the things I wanted from my boyfriend, he was never going to be, I get really jealous anyway, so I couldn’t fight with girls and boys."
The bisexual boyfriend news isn't the only bombshell in the book. Shapiro also writes that Adele loves drama and drinking, thanks to her tumultuous family life.
