SO, TATTLE was watching the Billboard Music Awards on Sunday night when an important cultural shift took place.

Justin Bieber got booed.

And he didn't take it well.

The Biebs, you see, fashions himself an artist.

"I'm 19 years old," an obviously stunned Bieber said accepting the first-ever Milestone Award. "This is not a gimmick. I'm an artist and I should be taken seriously and all this other bull should not be spoken of. I want to thank my manager, Scooter Braun. I want to thank my family at home. I want to thank my mother, my father. I want to thank Jesus Christ."

1) It's not up to you to declare yourself an artist.

2) If you have to tell people you "should" be taken seriously, you probably shouldn't be taken seriously.

3) Wearing MC Hammer pants and singing with your voice auto-tuned beyond human recognition is most definitely a gimmick.

There was so much synth-aided singing and lip-synching during the Billboard show that it even embarrassed Kid Rock, who broke the cardinal rule of these made-for-TV events and said something critical.

Presenting the award for Top Rap Song, Rock exhorted the crowd, "Let's give it up for people lip-synching under prerecorded music."

Yikes!

But let's be real, music industry, the overwhelming fakeness was embarrassing and most of the music was almost instantly forgettable.

And when will.i.am got the Biebs to join him for another egomaniacal paean to himself, "That Power," Tattle began to think back to the songs of our grandparents' generation and imagine a composer like Cole Porter getting on stage and robotically singing:

"My name is Porter/Drink Scotch not water/So hide your daughter/Or she'll be out/And about/Doing all that I taught her. I'm the top."

Now you see him

 Jesse Eisenberg stopped in Philadelphia last Friday to promote his upcoming magic movie, "Now You See Me," and hopped out of a limo in front of the Ritz-Carlton. On the sidewalk were a group of Reds fans holding baseballs and looking for autographs. They saw Eisenberg, star of "Zombieland," and asked him to sign.

The actor was a bit baffled to see the baseballs, but happy to oblige.

"It's kind of a childhood fantasy to sign a baseball for somebody. I never thought it would happen; now it has."

A Marky event

Hey, ho! Let's go!

Marky Ramone - yes, that Marky Ramone - has just been added to an already star-studded lineup at this year's Wizard Philly, May 30-June 2, at the Pennsylvania Convention Center. It is the first time the legendary rocker will be appearing at Wizard Philly.

Wizard has also just announced that Gina Torres ("Firefly") will be gracing the con.

But perhaps the biggest announcement for fanboys is that Marvel Comics is coming back to Philly after too long an absence!

"We are excited to bring an industry leader like Marvel to Wizard World shows," John Macaluso told Comics Guy Jerome Maida. "Many of our fans have a close connection with the movies, comics and characters Marvel produces, and these two panels and review sessions are excellent addition to our lineup."

The panels are entitled: "MARVEL: Breaking Into Comics the Marvel Way," set for Friday at 5 p.m. and "MARVEL: From NOW! to Infinity," to take place Saturday from 4 to 5 p.m. Additionally, Marvel will be accepting portfolios on Friday and Saturday, and talent scout C.B. Cebulski and others will conduct reviews on Saturday and Sunday from 2 to 3:30 p.m. in Room 110.

TATTBITS

Seth MacFarlane is too busy to host the Oscars in 2014.

The multitalented comedian says on Twitter that he "tried to make it work schedule-wise, but I need sleep."

The creator of "Family Guy" suggested Oscar producers tap the eccentric actor Joaquin Phoenix to host the show.

Robert Pattinson and Kristen Stewart have reportedly broken up again.

* According to London's Daily Star, the lads of One Direction have nicknamed Harry Styles "Mrs. Mop."

Coincidentally, Tattle has been nicknamed "Mr. Mope."

Harry is reportedly a neat freak and has become Felix Unger to the group's Oscar Madison, to make sure their tour bus stays tidy.

"He went to a supermarket and bought a ton of cleaning products, as he didn't think the bus was clean enough," said an unnamed source.

"He watches to make sure no one drops food anywhere and asked people to leave their shoes at the door and wear slippers."

Maybe that's the reason for his split with Taylor Swift.
