Taylor Swift tipped a bunch of service staff working the Grammys … slipping them cash on her way out … and it’s all on video.

New footage shows Taylor walking in the hallway in what appears to be Crypto.com Arena in downtown Los Angeles — where the award show was held — before she stops and hands out cash tips to a group of servers.

Taylor is walking past when she’s overheard saying, “Thank you so much for all your hard work” and then it looks like she recognizes the servers and doubles back to give them a fat tip.

Wild scene from Super Bowl week — when Patrick Mahomes Sr. got in a shouting match with fellow ex-MLB pitcher John Rocker right in the middle of Bourbon Street … and things grew so intense, the two needed to be held back from each other.

Or … was it all a set-up to promote a celebrity boxing match??

Footage of the apparent altercation is making rounds on Tuesday … showing Pat Sr. chatting with some buddies as the former Atlanta Braves hurler approached him.

The two sides jawed back and forth … and eventually, the guys Mahomes were with intervened and got them away from each other.

A lot of words were exchanged … and while it’s hard to make out exactly what was said, it doesn’t sound too nice.

In fact, as Pat. Sr. walked from the area, Rocker threw his drink near Mahomes’ feet.

It’s unclear when exactly this happened — we reached out to both sides for more information.

But one thing definitely worth noting — Barstool Sports founder Dave Portnoy said just days ago Rocker and Mahomes Sr. are expected to fight in a future Rough ‘N’ Rowdy boxing event … so take that into consideration.

Regardless, Rocker commented on the video just minutes ago … saying, “This f***ing loser can’t take a damn joke.”

“Wish I laid him out right there and ruined his bulls*** weekend even more.”

Rocker played for the Braves, Cleveland, Devil Rays and Rangers during his career … but was possibly more known for being a controversial figure (to say the least).

4:48 PM PT — Amazon spokesperson Steve Kelly tells TMZ … “We’ve reached out to Ms. Moore via Instagram to apologize for this and to ask for more information from her in-laws so we’re better able to investigate what happened here.”

He continues … “For weeks, we’ve advised those who are delivering on our behalf in southern California to use discretion in areas that were impacted by wildfires – especially if it involves delivering to a damaged home – that clearly didn’t happen here.”

Mandy Moore is taking Amazon to task after one of the company’s drivers delivered a package to the home of the star’s in-laws, which was burned to the ground in the Los Angeles wildfires.

On Tuesday, the actress jumped on her Instagram Stories and posted a pic of the charred remains of her in-law’s Pasadena house. The photo contained a brown box — wrapped in what appears to be an Amazon label — resting in front of the decimated property.

In the caption, Mandy — clearly shocked — didn’t hold back her contempt, saying, “Do better, Amazon. Can we not have better discretion than to leave a package at a residence that no longer exists? This is my mother and father in law’s home. Smh.”

But Mandy’s in-laws weren’t the only ones in the family impacted by the wildfires. Mandy’s Altadena home was also damaged by the infernos with only the main section of her house still standing after the fires were put out.
