Pete Davidson has joined the diaper squad … his girlfriend Elsie Hewitt has given birth!

Yup, the model officially announced the arrival of their newborn on IG Thursday … sharing photos of their little one. She says her baby girl, Scottie Rose Hewitt Davidson, was born on December 12, 2025 … last Friday.

Pete and Elsie were soaking up the soon-to-be-parent vibes over the summer … relaxing on luxe getaways and enjoying some much-needed chill time together.

TMZ spilled the tea — the former “SNL” star and Elsie have been expecting since July, after sparks flew back in March.

Pete’s been a doting dad-to-be in the run-up to the birth … carrying his GF’s pregnancy pillow for him on his shoulders while walking through NYC — and, we also got video of Pete planting a kiss on her lips at the baby shower.

The duo got together after Pete’s high-profile heartbreak tour — Kim Kardashian, Ariana Grande, Emily Ratajkowski … you name it.

The gang’s not all here for a “Stranger Things” event in New York City … because David Harbour and Millie Bobby Brown are noticeably absent.

Most of the cast was at the “Stranger Things: The Final Season Celebration” at New York City’s Paley Center Thursday … but David and Millie were nowhere to be found.

As we reported … David was initially supposed to attend the event, but he was scrubbed as an attendee on the event website.

David’s absence comes on the heels of some bizarre behavior in Encinitas, CA. He’s had a tough year, going through a messy divorce with Lily Allen.

Millie wasn’t scheduled to attend either, and she didn’t make a surprise appearance.

There’s been a rumored feud between David and Millie, but we’ve seen them together at other “Stranger Things” events recently.

According to our law enforcement sources, the unidentified suspect was found with a self-inflicted gunshot wound at a storage facility in Salem.

As you know … two students were killed and nine people were injured during the shooting over the weekend at the Rhode Island campus — and police have been frantically searching for the shooter since.

They brought a person of interest into custody shortly after the shooting — a 24-year-old Wisconsin man who was later released.
