The rented Hollywood Hills mansion D4vd once called home — when the body of 15-year-old Celeste Rivas Hernandez was found in the trunk of his Tesla — is getting prepped to go back on the market, The Post has learned. The four-bedroom, four-bath, 4,315-square-foot pad will soon be available to rent for $20,000 a month, according to real estate agent Alex Micic.
