Demi Lovato Has Agreed to Go to Rehab

Demi Lovato has agreed to go to rehab, and plans have already been made with the facility ... TMZ has learned.

Sources with direct knowledge tell us, Demi's family has squarely raised the issue of rehab with her ... something they delayed for days because of the many complications resulting from the OD. Demi was very sick and her family did not want to upset her with something that might trigger conflict.

We're told she's still at Cedars-Sinai Medical Center, but one source says, "She's getting out any day now." Our sources say there will be no transition ... it's right from Cedars to a live-in rehab facility.

We do not know which facility Demi will enter and whether it's in California or another state.
