Jason Kelce says Taylor Swift has had a “staggering” impact on Travis Kelce … revealing his little brother has grown up tremendously since he began dating the pop star.

Jason got candid about the Chiefs tight end’s relationship with Taylor on Tuesday’s episode of the “Fitz & Whit” podcast … explaining to former NFL stars Ryan Fitzpatrick and Andrew Whitworth he’s noticed a huge change in his bro since he began shacking up with Swift nearly two years ago.

“It’s been staggering, honestly,” he said.

Rick Buckler, the drummer for the legendary rock band The Jam, has died after a brief illness.

His death in Woking, UK was confirmed on X by his former bandmates, with Paul Weller reflecting on their journey from bedroom rehearsals to achieving more than they ever dreamed — saying what they created still stands the test of time.

Rick’s other former bandmate, Bruce Foxton, called him a great drummer whose innovative beats helped shape their iconic songs, including “Going Underground” — and he also expressed how grateful he was to have had the chance to work with him as much as they did.

The trio met in school, and they formed The Jam in ’72. Their debut album, “In the City,” dropped in ’77, and they went on to release several albums and four number-one singles before breaking up in ’82.

Rick took a break from music in the mid-’90s to work as a carpenter, but made a comeback in 2005 with a new band, The Gift — which Bruce later joined — and they toured together from 2007 to 2009.

Rick is survived by his wife, Lesley, and two children.

He was 69.

New twist in the Karen Read case … the judge just suspended an evidentiary hearing after voicing “grave concern” over new information from prosecutors.

A hearing in Read’s retrial was moving along normally Tuesday when suddenly Judge Beverly Cannone called for a recess.

The swift change happened on the heels of special prosecutor Hank Brennan moving to exclude testimony from two crash reconstruction experts who were involved in the federal investigation into her case.

Judge Cannone said the new info from prosecutors was not only concerning, but also “may have profound effects on this defense and defense counsel.”

The crash reconstruction experts testified as defense witnesses in Read’s first trial, when they told the jury O’Keefe’s injuries were inconsistent with being hit by a car.

In the first trial, Read’s defense team claimed the crash experts were NOT hired by her defense … but in Tuesday’s hearing, prosecutors told the court they had information the crash reconstruction firm billed Karen’s defense team $23,925.

Read’s attorney, Alan Jackson, was reportedly asked outside the courtroom if he paid crash experts to testify … and he denied it.

Karen’s first trial ended in a mistrial after a jury voted to acquit her on charges of second-degree murder and fleeing the scene of an accident … but split on vehicular manslaughter charges, deadlocking 9-3 in favor of conviction. She’s set for a retrial in April.
