Where in the world is Justin Bieber’s mother?

Where are Miley Cyrus’ dad and mom — folks whose lone act of parental concern was to give their girl permission to ink her body with tattoos?

I’ve had it up to here with this generation of junior celebs who use their fame as an excuse for behavior one wouldn’t accept from a street hustler.

All over America, children, some not long out of diapers, are in for trouble. Years ago, kids wanted to grow up to be like their teacher, big brothers or sisters.

Now, it’s all Miley and Justin, all the time.

In just a few months, Bieber, the 19-year-old diminutive Canadian pop star, has devolved into a human train wreck. He’s Amanda Bynes, without the wig.

The long series of appalling behavior hit a climax when Biebs was seen in a videotape obtained by TMZ.com, laughing earlier this year with his buddies while relieving himself into a mop bucket in the back of an unidentified New York restaurant. The entitled pipsqueak was apparently too self-involved to consider that a minimum-wage-earning fan might be required to clean up after him. Bieber was then seen spraying cleaning liquid on a photo of Bill Clinton, unloading an F-bomb at the former president. He later apologized to Clinton. Not to the working people of New York.

The disgusting behavior should have sent Bieber into a new career in fast-food management. It probably won’t.

Though technically an adult, Bieber behaves like a toddler in a tantrum. He should not walk free without adult supervision. But who will step in?

The bad behavior is amping up. Bieber drove over 100 mph in a 65-mph zone on a California highway last year. The paparazzi made me do it, he complained.

Biebs had to be restrained by his own bodyguard this year in London as he cursed at and lunged at a photographer. Drugs were found on his tour bus (but were not linked to Justin). His pet capuchin monkey, Mally, was seized by customs agents in Germany. In Poland, he walked, bizarrely shirtless, through airport security. He also passed out onstage in London.

In April, while visiting the Anne Frank House in Amsterdam, where Anne hid before dying in a Nazi death camp at age 15, he enraged Jews and people of good conscience.

“Truly inspiring to be able to come here,” he wrote in the museum’s guest book. “Anne was a great girl. Hopefully she would have been a belieber” — a Bieber fan.

Who’s minding the miscreant? The mother who raised him sounds more like a pal than a parent.

“You know, you’ve got to love them and encourage them, and he knows what I think. He knows the things that I disagree with,’’ mom Pattie Mallette indulgently told “Fox & Friends’’ last week. “But he also knows the many things that I’m really proud of him for. He does a lot of great things that don’t show up in the headlines.’’

Miley has fallen low since her seemingly wholesome days starring in the Disney Channel’s “Hannah Montana.” She was voted Worst Female Role Model in a recent online poll of parents by CouponCodes4u.com, beaten out on the male side only by Rihanna-basher Chris Brown.

Today Miley, 20, parades onstage in her underwear. She referred to herself as a “stoner” in a video in which she appeared with a bong. Miley, who may or may not still be engaged to actor Liam Hemsworth, was taped eating a cake shaped like male private parts.

But don’t expect Miley’s parents to intervene. Country-singer dad Billy Ray Cyrus defended Miley against parents who complained when she gyrated like a stripper on a pole during the Teen Choice Awards in 2009 — when Miley was 16. That year, she was also videotaped bumping and grinding against a 44-year-old man.

“I just think that Miley loves entertaining people,” he told “Access Hollywood.”

A year earlier, Billy Ray posed like a lover with his then-15-year-old daughter, who was draped in a sheet, in a Vanity Fair spread.

She was seen this month gyrating in hot pants and stiletto boots against a female dancer on “Jimmy Kimmel Live.”

And Mom?

Miley and mom Tish Cyrus were photographed at the beach, showing off large and seedy tattoos, the first of which Miley is said to have received at age 17 with her parents’ permission.

The good news is that my daughter is done with Miley and her trashy ways. She’s a role model no more.

But there are lots of other kids ready to take her place.

Be afraid.

Spank you, veterans

Eleven gray-haired Vietnam veterans and an 83-year-old World War II hero were convicted Friday of trespassing. The vets were charged with crimes after they refused to stop reading the names of the dead “in a timely fashion’’ at a memorial.

After finding the men guilty, Manhattan Judge Robert Mandelbaum dismissed the convictions, in the interest of justice. That’s it?

Twenty-five mourners were flex-cuffed, frisked and tossed in a police wagon last October after they refused to stop reading names of the dead by a 10 p.m. park curfew at the Vietnam Veterans Plaza downtown. The judge could have honored these brave souls by freeing them with a “thanks for your service’’ instead of a conviction.

This episode brings shame on our city.

Scientology’s fallen star rises

“King of Queens’’ TV star Leah Remini has dealt a crushing blow to the Church of Scientology.

Remini is done with the star-studded faith of Tom Cruise and John Travolta, Page Six reports.

At the 2006 Tom Cruise-Katie Holmes wedding, sources said, Remini asked about the whereabouts of church leader David Miscavage’s wife, Shelly, who reportedly hasn’t been seen in public since 2007.

Remini is said to have been cursed at by the ex-Scientology Celebrity Centre head and subjected to interrogation and five years of “thought modification.’’

The church denies this.

Remini dislikes its practice of breaking up families by forcing followers to “disconnect’’ from relatives who leave the church. Well, Leah is from Bensonhurst.

Don’t mess with a Brooklyn gal!

Spitzer: wherever egos, I go

Eliot Spitzer paid big bucks for a service most people perform for free.

Spitzer, the hooker-happy ex-Love Gov who wants to be city comptroller, reportedly paid canvassers up to $800 a day to collect signatures aimed at putting his name on the Democratic primary ballot. Spitzer then delivered 27,000 signatures to the Board of Elections, seven times more than he needed.

Jay Leno asked Spitzer on “The “Tonight Show” Friday— “How can you be this stupid’’ to cavort with hookers?

The answer is simple: There seems no limit to Spitzer’s stupid egotism.

She’s the one with cojones

Anna Graham, wife of renowned Russian sculptor Ernst Neizvestny, stared down a thug holding a gun to her head outside her Soho building and coolly told him, “You don’t have the b—s” to pull the trigger. She was right.

But last week, she told The Post that the July 3 standoff wasn’t worth the risk. Give up your possessions, she advised — and run.

Smart words. Still, I wouldn’t challenge this spitfire.
