The 25-year-old singer said it was a "very cliquey" party.
"I had a terrible experience. This one celebrity was a complete b**tch and was miserable to be around. It was very cliquey... I remember being so uncomfortable that I wanted to drink," Lovato, who has been sober for six years, told Billboard.
She said she ditched her party clothes but went to the 10 pm meeting wearing her diamonds.
