Ellie Goulding has revealed she turned to alcohol after struggling to adjust to life in the spotlight.
"I had to be a fake person to deal with the surreal situation I was in," the pop star said.
"Usually for me it involved alcohol. I assumed I couldn't be good enough, smart, funny, or crazy enough to be with certain people without it."
The singer made the comments while appearing on Fearne Cotton's Happy Place podcast.
As well as admitting to drinking alcohol prior to interviews, the 32-year-old also revealed she turned to booze before appearing on Radio 1's Live Lounge - which is usually recorded in the morning.
"Live Lounges used to be the most nerve-wracking, I even drank before those.
"I would say, 'Right, I've got to drink this morning because I've got this interview and I don't really know how to answer the questions, because I don't really know who I am any more.'
"I thought drinking would at least make me a bit more funny, or interesting," Ellie Goulding said.
