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.

Music superstar Bad Bunny is in a bit of hot water after putting his paws on a protected museum exhibit in Mexico on a recent visit … and he even posted pics of his transgression.

Now that Bad Bunny’s done with his ongoing residency in Puerto Rico, he’s been playing tourist … and at a stop in Mexico City, the singer visited the National Museum of Anthropology to take in the culture.

Like most museums, visitors are not allowed to handle objects or displays … but as you can see from one of the pics BB posted himself — he’s since taken it down — he took a moment to lay hands on a stone monument carved with ancient insignia during his visit.

Spanish-language news site KCH FM reports museum security reacted right away during the December 17 incident and warned him to keep his mitts off the goods. The museum officially posted a reminder on socials to the public that no matter how famous you are, you gotta respect the history, and the rules … don’t engage in “Direct manipulation of an archaeological stele” … the technical term for the carved stone monument.
