Demi Lovato is "awake and with her family" after she was rushed to hospital following a suspected overdose. 

The 25-year-old singer was taken to Cedars-Sinai Medical Center in Los Angeles on Tuesday and her family have now thanked her fans and pals for their "love, prayers and support". 

A rep for the 'Sorry Not Sorry' hitmaker said in a statement: "Demi is awake and with her family who want to express thanks to everyone for the love, prayers and support.

"Some of the information being reported is incorrect and they respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now."

Law enforcement sources initially told TMZ that Demi had apparently overdosed on heroin, but a source close to the singer has now told the gossip website that is not the case.
