A worker at Arrowhead Stadium on Christmas got the shock of her lifetime when Taylor Swift dropped a massive tip … a gesture so shocking, the suite staffer had to frame one of the six fresh Benjamins.

TMZ has learned a viral Facebook post from a stadium employee named Robyn Gentry talking about the superstar’s Xmas generosity is legit … TS indeed tipped $600 to the unsuspecting worker.

As Robyn tells it … TS was at the Christmas game to watch fiancé Travis Kelce play maybe his last NFL game … and superstar was so appreciative of staff working on the holiday, she was handing out her own gifts … that being cold hard cash.

Robyn explained the money was her “whole paycheck for two weeks” and she was so touched, she had to frame one of the bills. Although as of her Sunday post … she still had not spent any of the $600.

Needless to say … it didn’t take long for Swifties to see the post — and make it go viral with shares and comments.

The tragic crash that injured Anthony Joshua claimed the lives of two people close to the boxing superstar — his trainers and longtime friends, Sina Ghami and Kevin “Latif” Ayodele, according to the president of Nigeria, Bola Ahmed Tinubu.

The politician shared his condolences in a statement released minutes ago … saying he spoke directly with AJ regarding the devastating losses.

In their conversation, Tinubu said Joshua assured him he is receiving the “best possible care.”

He also posted a link to a fundraiser to build a mosque and a borehole for Latz.

Chris Eubank Jr. and Joshua’s boxing opponent, Jake Paul, also shared their thoughts and prayers.

“Life is much more important than boxing,” Paul said on X. “I am praying for the lost lives, AJ, and anyone impacted by today’s unfortunate accident.”

The Federal Road Safety Corps (FRSC) in Nigeria said preliminary reports show that Joshua was sitting in the back of a black Lexus SUV, which is “suspected to be travelling beyond the legally prescribed speed limit on the corridor.”

The driver of the truck lost control and crashed into a stationary truck on the side of the road.

Sally Struthers was seen in public on Monday … weeks after her “All in the Family” costar Rob Reiner and his wife Michele were brutally murdered in their Brentwood home.

Sally was snapped out and about in Los Angeles … and her mood appeared to be glum … understandable given the recent double killings that rocked Hollywood.

TMZ broke the news … Rob and Michele were butchered in their home on Dec. 14 … and their son Nick has since been arrested and charged with their murders.

Among the countless fans and industry collaborators most recently paying their respects to Rob and Michele was Martin Scorsese … who penned an essay for the New York Times published on Christmas.

Martin said he bonded with Rob over being New York transplants in Hollywood and retold some jokes Rob made at various dinner parties over the years … and he praised Rob’s directing and acting skills.
