John Feinstein — a longtime sports reporter and author — has died at the age of 69 … according to his employer, the Washington Post.

John’s brother — Robert — confirmed his passing to the outlet on Thursday. His cause of death was not revealed.

Feinstein started his career at the Post in 1977 … working as a night police reporter before joining the sports beat. He was the author of 48 books, 23 of which became a New York Times best seller. One of his most well-known pieces was “A Season on the Brink,” which followed the 1985-86 Indiana University men’s basketball team led by Bob Knight.

He had a column published Thursday morning by the Post … which was about Michigan State head coach Tom Izzo.

Many media members, along with readers of his work, have taken to social media to comment on his passing.

He was 69.

Gabby Windey says she hasn’t seen a dime from the prize money she won on “Traitors” … but there’s a paperwork issue holding up the payment and Gabby doesn’t seem to be sweating it.

We got the reality TV star at LAX and our photog asked her about her claim that NBC has not paid her the $40,860 she won on the show.

Gabby tells us she still hasn’t been paid since first raising the issue on “Watch What Happens Live” when she told Andy Cohen about it … and she’s hoping the deposit comes soon.

We’re told Gabby’s agent hasn’t submitted paperwork with her bank account routing number … and ya gotta see her reaction when we confronted her with that fact.

Aaron Goodwin‘s officially filed to divorce his wife … not exactly a shock since cops arrested her for allegedly trying to hire someone to kill him.

The “Ghost Adventures” star filed the document Wednesday in Nevada … asking the court not to award anyone alimony in the case while also requesting to be paid back for attorney’s fees.

In light of what’s going on, there’s really no mystery about the divorce filing … though it does say Aaron and his estranged wife Victoria‘s “views, tastes, likes and dislikes” have “become incompatible to the extent that it has become impossible for them to live together as husband and wife.”

We broke the story … Victoria was arrested last week after cops say she messaged a Florida inmate about killing her husband.

She and the inmate — Grant Amato — are alleged to have put aside $11K to pay someone to kill Aaron … who we later learned found out about the shocking news on the set of “Ghost Adventures” while cameras were rolling.

Victoria has denied she ever really wanted her husband killed … claiming she thought the money was for cell phones. Amato is currently serving time in prison for killing his mother, father and brother.
