Adele - Adele Got Drunk Before Concerts
Adele allegedly would drink so much alcohol before gigs that she couldn't stay upright on stage according to an unofficial biography.
Adele used to get so intoxicated before playing concerts that she once fell off a stool on stage.
The 'Rolling In The Deep' singer also forgot the words to one of her songs according to a new biography.
She described her memory lapse as ''the worst thing ever'', according to the book out next month.
The star's unofficial biographer Marc Shapiro told In Touch magazine: ''Midway through her first tour, she allegedly had a drinking problem.
Apparently she told him in an interview: ''I got so drunk by the time I went on at 2 am I had forgotten the words to my own songs ... It was the worst thing ever.''
The author continued: ''Adele would drink more than normal to salve the heartbreak.''
According to his book Adele: The Biography, her bisexual boyfriend cheated on her, leaving the 24-year-old distraught.
He continued: ''She loved the drama surrounding boys who treated her badly.
''She had a fairly good self-image and seemed to handle it okay on the surface, but I'm sure it bothered her on a deep, emotional level.''
