Bleepin' hell, has teen phenom Justin Bieber reached the inevitable "diva" phase of his career?

Roger on that, so says one Aussie TV co-host who claims the singer chucked a tanty and hurled an F-bomb at a floor manager last month.

The word according to Sunrise co-host David "Kochie" Koch is that Biebs purportedly got testy with a floor manager during an appearance on the breakfast show.

Bieber's appearance on the show last month caused chaos when police had to control 4000 hysterical fans.

Koch claimed on a Sydney radio show this week that the dulcet-toned 16-year-old warbler swore at the crew member when he showed him where to perform on the set.

Koch told radio station Mix FM: "We had him on and he was a thoroughly nice bloke, really decent guy.

"Our floor manager was directing him to where he was about to perform and he turned around to (floor manager) Nick and said 'don't ever f***ing touch me again'. Nick went 'What?'

"And then (Bieber's) sound guy...said 'don't take offence mate he tells us that all the time'. So I was a little disappointed in that ... I thought maybe someone needs to drag you aside and give you a bit of a slap."

Now now, violence solves nothing. Better off sending him to bed with no supper.

Anyway, Biebs has vehemently denied having a diva strop on the show. He took to Twitter this week and trashed the host's claim, saying: "Family time with my mom couldn't come at a better time....I was raised to respect others and not gossip...nor answer gossip with anger," he said.

"I know my friends family and fans know the person I am. Hearing adults spread lies and rumours is part of the job I guess."

Yup, welcome to the neighbourhood, Biebs.

Bolstering the diva talk is this other yarn we clapped eyes on earlier this week.

Asked by a radio presenter about his new ink during an interview at a music festival in Wales recently (yes, he was on my home turf. Bangor of all places, no less), he reportedly flipped her the birdie and stormed off in a backstage buggy.

Yeah right.

His "people" had supposedly vetoed any probing questions about his new tat.

Oh, and the Welsh apparently didn't get into the Bieber groove. He was reportedly booed by crowds at the event before his performance of hit single Baby.

Sorry Biebs, I feel ashamed. I'll have a word with them all when I hit the home turf.

In other Bieber news...

It's not the gossips who are Bieber's enemies. Oh no, it's doors the wee chap has to watch out for.

Y'all have seen the video of him slamming his head on a revolving door last week. Well, he's done it again:

"Yes, it is true...I almost nailed my head on a glass door again...almost," he tweeted.

Poor guy. Maybe it's time to cut that fringe, dude?

Now that

Megan Fox

has been booted off the

Transformers

franchise, the role of bot-battling bodacious babe is up for grabs.

We hear that model

Rosie Huntington-Whiteley

has

to replace Fox. Sadly, plastic princess Heidi Montag didn't get that memo.

So desperate is she to get the leading lady part in the threequel, she's made her very own "audition" video to pitch for the role.

She even tweeted the sad spectacle to director Michael Bay. But, as it turns out, she sent it to an impostor's Twitter account. Shhh, don't tell her though.

Shame Bay never clapped eyes on it. She was born for the part.

Sticking with the synthetic one...

Heidi Montag

says her recent plastic surgery marathon is the best thing she's ever done.

She tweeted this week: "My last surgery was the BEST decision of my life! Anything else anyone says (family members who are trying to make money off of me) is a lie!

"I have never felt sexier, happier, or more amazing in my own skin. I truly look the way I have always dreamed, I love America and freedom! You will get to know the true me and my REAL life VERY soon, under all my plastic haha! Not the Superficial 'me' you read about and watch!!!"

But there is a catch. The human Barbie is packing a sad because she has no mates.

"PS. I HAVE NO FRIENDS, the ones who are pretending to be 'friends' or 'family', are crazy, angry, broke, and bitter...They haven't been in my life for years! LIARS!"

Hmmm, and she wonders why she's a Martha-no-mates...

Really?

The mag claims the Travoltas "who are already parents to 10-year-old daughter Ella, are expecting twin boys!"

Sorry guys, it's just not true.

A rep for the Travoltas has trashed the report, saying it's "Totally false, not true. They are not having twins."

Monjack update

Monjack was found dead on Sunday in the home he shared with Murphy. An autopsy has been carried out on the late screenwriter, but the official cause of death won't be known for weeks, pending toxicology results.

Word is Monjack will be interred at Forest Lawn Memorial Park in the Hollywood Hills today.

RIP.

MiMi preggers?

Is the human dolphin with child? Yes, we're back on

Mariah Carey

bump-watch.

Tongues are wagging again that Carey's pregnant - because she abruptly pulled out of a film project.

Carey had signed on to star in the adaptation of Ntozake Shange's 1975 play

For Colored Girls Who Have Considered Suicide When the Rainbow Is Enuf

.

But she's pulled out; a month before shooting was due to begin.

Her rep has since released a rather vague statement, saying: "I'm not at liberty to discuss her personal life at this time."

Publicist

Cindi Berger

added: "She is not doing the movie because her doctor advised her not to.

"More than that I cannot comment further."

Now that sounds decidedly fishy to us.

Not preggers, no doubt

Sticking with the bambino theme, we can reveal that

Gossips even had her supposedly wearing one of those bracelets to help stop morning sickness.

But she
