The star was taken by ambulance to Cedars-Sinai Medical Center in Los Angeles. She has since been released and is recovering at home.
Love was attending a party organised at the Roosevelt Hotel on Thursday night when she became ill.
The star talked about the incident to the New York Daily News, "I don’t quite know what happened It was very hot I had two Diet Cokes I started feeling really woozy I decided to go to the private cabana that they’d given me to use I must have fainted."
"A friend called an ambulance, and I woke up in hospital on a breathing machine They didn’t keep me there long."
Although the authorities confirm that they responded to a call for a drug overdose, Love denied that her illness was caused by drugs. The singer – who had a negative drug test just last week – adamantly insisted, "I didn’t work for a year on sobriety to blow it You have my word on that."
