Jay North — a veteran actor who played the eponymous character in the 1960s sitcom “Dennis the Menace” — has died … TMZ has confirmed.

Laurie Jacobson — a longtime friend of North and wife to “Lassie” actor Jon Provost — tells TMZ … Jay passed away Sunday at his home in Lake Butler, Florida after a battle with colorectal cancer.

We’re told his health started to deteriorate over the past month, and he was surrounded by family — his wife Cindy and her daughters from a previous marriage, which we’re told he “adored” — when he passed.

By the late 1980s, North left acting behind … making limited cameos as himself in the years since on an episode of “The Simpsons” and in the David Spade movie “Dickie Roberts: Former Child Star.”

In more recent years, North worked as a correctional officer in Florida … reportedly helping troubled youth in the juvenile system. He also helped counsel former child stars via the group A Minor Consideration through the 1990s.

Despite his distaste for Hollywood, Jacobson says Jay did appreciate one perk he got from the industry — lifelong friends who were also child stars around the same time including Angela Cartwright, Jerry Mathers, Stan Livingston, Paul Petersen and Brandon Cruz, among others.

Jay was 73.

Michelle Williams ain’t going to “Cater 2 U” if you’re taking your shoes off on an airplane … taking to social media to call out her seatmate who went barefoot on a flight.

The singer-songwriter hopped on Instagram to express her displeasure with the person sitting next to her … sharing a snap of their toes — totally uncovered and poking out from behind the seat barrier.

Michelle wrote, “I PROMISE YOU BETTA GETCHO FOOT FROM ME!!!! Y’all this is happening neowwwwwwww on my flight and I am crying real tears!!”

MW jokes she accidentally elbowed the foot — so, she’s gotta take her jacket to the cleaners … before lamenting how people in first class feel they can just do whatever they want on planes.

Williams has been busy on Broadway recently … starring in “Death Becomes Her” — the musical based on the 1992 film starring Meryl Streep and Goldie Hawn.

She starred in the original cast in Chicago last year … playing Viola Van Horn — an original character name based on Lisle von Rhuman, who is played by Isabella Rossellini in the OG flick.

Ne-Yo brought all the ladies in his life on a special date night … bringing out all four of his girlfriends to a club where he performed — and, engaging in some PDA on the dance floor.

The rapper surprised the crowd at Slate NY, a popular nightclub in New York City’s Flatiron District … walking through the front door with all four of the women he’s in a relationship with.

After the whole crew pulled up looking ready to party, Ne-Yo hit the stage … playing some of his most well-known songs for the packed crowd.

Later on, Ne-Yo was spotted on the floor … locking lips with one of his GFs — and grabbing a handful of her behind, too.

We’ve talked with Ne-Yo about his polyamorous relationship before … and, he advocated to give polyamorous couples the right to marry — though he admitted matrimony wasn’t for him.

He was walking with two of his GFs at the time … and, while he currently has four, he also told us there’s no cap to the number of partners he’d have at any given time.
