Demi Lovato's friends wanted to keep her OD on the DL ... asking paramedics to come to her house without sirens.
In the 911 call from Lovato's house -- obtained by TMZ -- the caller remains calm while taking orders from the dispatcher. As the ambulance approached, the dispatcher let the caller know they'd soon hear sirens to which the caller responded, requesting they be shut off ... seemingly to keep the situation private from neighbors. However, the dispatcher says that's just not possible.
Check out the initial dispatch audio (below). You hear the dispatcher for the L.A. Fire Department calling LAPD and saying, "I thought maybe you guys better go on something like this." It's unclear if he's saying the LAPD should go out because Demi is a celebrity, or because of a drug overdose. The call is redacted, so we don't know if Demi's name or the OD was mentioned.
