Even though it’s been a foregone conclusion for months, Deion Sanders is finally confirming his romance with Karrueche Tran by taking a meaningful step in their relationship — going Instagram official.

Coach Prime shared a pic to his IG Story on Sunday, flashing his pearly whites with Tran cozied up on his shoulder sporting a smile of her own.

Of course, Prime’s post came after his son, Shilo, already spilled the tea on his YouTube channel … where he shared a nearly 15-minute home video of the family’s Christmas at Deion’s mansion.

Later in the clip, Sanders and Tran arrive, and Shilo opened his gift from the couple while they sat together on the stairs, all lovey-dovey.

Shilo — who was waived by Tampa Bay during final roster cuts this season — even thanked Tran for the Fear of God ESSENTIALS outfit … and she jokingly called him “stepson.”

Tran and Sanders spoke about their Christmas together at the Browns vs. Steelers game on Sunday — saying they had a great holiday with family.

The dating rumors first surfaced a few months back when Tran appeared in Deion Jr.‘s vlog, showing the NFL Hall of Famer at the hospital for treatment related to blood clots.

She’s been around the Sanders fam ever since … and let’s face it, everyone knew what it was.

Philip Rivers hopped off the couch just to go 0-3 in his surprise NFL comeback at 44 years old … but the Indianapolis Colts quarterback isn’t lamenting his decision — telling reporters he’d do it all over again.

The formerly-retired star met with reporters after losing 23-17 to the Jacksonville Jaguars on Sunday … and he explained he has just one regret about his return to the field after five years away from the game.

“I told you guys I wasn’t going to have any regrets about coming back — and I don’t,” Rivers said in his postgame presser. “Other than us not winning, it’s been an absolute blast for three weeks. If I go back and say, ‘All right, now you know everything’s going to happen, what are you going to do?’ I’d do it all again. It’s been absolutely awesome.”

Rivers — who rejoined the squad after starter Daniel Jones went down with a season-ending Achilles injury — did a solid job considering he was coaching high school football before getting the call … throwing for 544 yards with four touchdowns and three interceptions in his three-game run.

Cardi B and the B stands for brrrr — the rapper was no match for the cold temperatures as she supported her man, Stefon Diggs, during his game against the Jets on Sunday … leaving the Patriots star wondering if she bailed!!

The “Outside” rapper took shelter during the New England’s 42-10 win over New York at MetLife Stadium … where Diggs secured 101 receiving yards and one touchdown, earning himself a $500K contract bonus in the process.

Diggs, 32, wanted to celebrate with this girlfriend on the field … but realized she was MIA.

The friend told Diggs she was inside because the 30-degree temperature wasn’t her vibe … and even put Cardi on FaceTime to prove it, holding up the phone so Diggs could see his girl all warm and cozy inside while he stood there freezing on the field.

“I’m coming down,” Cardi said, “Wait for me.”

Her outfit definitely played a role in her mad dash for the heaters — Cardi came out to the frigid NY game with a Malibu Barbie-esque ‘fit, rockin’ a jean Chanel skirt and pink jacket with pearls.
