Singer D4vd will likely face murder charges for the death of Celeste Rivas, and that’s because the grand jury that’s hearing the case will be asked to hand down an indictment … sources tell TMZ.

There was a report last month that the grand jury was an “investigative” grand jury … a grand jury that helps authorities gather evidence but one that does not indict. An investigative grand jury can be useful to subpoena and then force uncooperative witnesses to testify.

Our sources say, however, the grand jury that has been hearing witnesses in the Celeste Rivas murder is actually one that will vote on indictments, and multiple sources tell TMZ that authorities — including prosecutor Beth Silverman — believe D4vd was involved in the death of Rivas.

TMZ broke the story … earlier this month D4vd’s day-to-day manager, Robert Morgenroth, testified for days. A TMZ reporter heard Morgenroth tell his lawyer in the courtroom hallway, Silverman was “very pushy” as to why he didn’t call the police. He said he responded by saying it wasn’t his responsibility and his job was to make sure D4vd’s tour kept going.

Grand juries generally do what prosecutors want … in no small part because the target — in this case D4vd — has no right to present a defense.

A police officer in Tennessee literally pulled a distraught woman back from the brink the day after Christmas — saving her life as she prepared to leap off a bridge … and it was all caught on video.

Watch the clip … the woman can be seen standing on the ledge of the Holston River Bridge in Knoxville, Tennessee. As Tennessee Highway Patrol and emergency responders stand by, the woman peers out onto the water, gathering herself to jump.

But in one heart-pounding moment, one of the officers lunges forward, grabs the woman by the waist and pulls her back to safety.

In a Facebook post, the Tennessee Highway Patrol wrote, “A woman was in a dark place and was considering jumping. Because people showed up and worked together, she is alive tonight.”

They continued, “This time of year can be especially hard. Many people are carrying things no one else can see. Stress, grief, loneliness, and fear can pile up fast. That does not mean someone is weak. It means they are human. If you are struggling, please hear this. You matter, and help is available … Today ended with a life saved. That matters.”

Following the rescue, the woman was taken by ambulance for an evaluation.

Alessandra Ambrosio was spotted soaking up the sun in Brazil with her boyfriend Buck Palmer … and the two were packing on plenty of beach PDA!

The supermodel and her jewelry-designer bae were snapped over the weekend … both rocking their chiseled bods at Cacimba do Padre beach in Fernando de Noronha.

Once they were off one another … Alessandra relaxed on the sand in her tiny white bikini — as she watched Buck ride the waves on his surfboard.
