A cautionary tale for parents who think their young children need access to social media.

A pervert pretending to be a friend of Justin Bieber and then Bieber himself, is in custody, TMZ.com reports, for targeting at least one young Belieber and convincing her to send him nude photos.

The girl was 9 at the time.

TMZ says Bryan Asrary messaged her a few years ago when he allegedly found her viewing Bieber's Instagram page. He told her he was one of Bieber's friends and he could arrange a text communication.

Next he told the girl he was Bieber and threatened her if she refused to send him nude photos of herself.

She sent nude selfies and a video. At 9 years old.

Because this first move wasn't twisted enough for Asrary, last year he contacted the girl again and threatened to publicly share the photos she sent him the first time if she didn't send him more photos.

This time, she told her mother and her mother called the police.

Asrary confessed and is now facing charges of extortion and child pornography. And it is too late now to say sorry.

TMZ.com also reports that Justin Bieber believes ex-girlfriend Selena Gomez using The Weeknd for promotion and that the pair is working on music together.

The Beebs, who's sounding a little jealous and used, says that Selena's new music often coincides with new collaborators which coincide with new boyfriends.

B-Street. Out.

Donald Trump may be the president-elect but he isn't the Boss.

And the B-Street Band, which pledges allegiance to both the flag and Bruce Springsteen, has decided to side with Springsteen and skip the New Jersey celebration of the Trump inauguration.

The inauguration may be a big deal, but it's a one-shot. The B-Streeters have been playing approximately 200 Springsteen sets per year for 36 years, according to Rolling Stone.

"We owe everything to [Bruce] and our gratitude and respect to the band is imperative above all else," keyboardist, manager, agent and publicist Will Forte told Rolling Stone.

"We felt that we had to make it known that we didn't want to seem disrespectful, in any way, shape or form, to Bruce and his music and his band," Forte said. "I don't want to upset them.... It became clear to us that this wasn't working and we just had to do what we thought was the right thing to do and that was to pull out."

The group had played the New Jersey gala for both inaugurations for President Obama and said it signed on for this show, nearly four years ago, before a Trump presidency was a gleam in anyone's eye.

"The band was caught in a hurricane," Forte said. "We didn't see this coming, of course."

Not many did.

TATTBITS

Since Russian oligarchs are in the news...

According to perezhilton.com, Mariah Carey and Elton John were paid a total of $4.22 million to perform at the wedding of the granddaughter of Russian billionaire Valery Kogan.

Irene Kogan, 19, wed Daniel Kevey at London's Landmark Hotel on Saturday, so Mariah and Elton didn't even have to fly to Moscow's Domodedovo Airport, one of the sources of the Kogan fortune, and the largest airport in Eastern Europe.

Mariah sang the couple's wedding song, "We Belong Together" and the reception lasted NINE hours–which is too long no matter how much money you have.

Also in attendance, music producer/DJ Mark Ronson and Antonio Banderas.

Tossing around money, however, is nothing new for Kogan. Forbes.com says he owns an $18 million home in Connecticut and both a $31 million apartment and a $100 million home in Israel–for when you just have to get out of the $31 million apartment.

When the Huffington Post ran a headline which read, "Florida Man Accused Of Repeatedly Sexually Assaulting Pit Bull," we first were stunned that could happen to the Miami rapper.

Then we saw the space and we were stunned that a Florida man sexually abused his family's own pit bull.

But it is Florida.

And the dog's name is Baby Girl.

Bradley Jean Hubbard, you need to meet Bryan Asrary. Maybe in prison.
