He can't get enough of himself! Justin Bieber lifts his shirt to show off his abs while giving model looks at Calvin Klein event in Hong Kong 

He has been working hard to rebuild his image after a string of run-ins with the law that included a DUI and a major fine for egging a neighbor's house in Calabasas.

But on Thursday Justin Bieber took a SMALL step backwards as he pulled some amateur moves on the red carpet for a Calvin Klein event.

Though he looked handsome and nicely groomed, the 21-year-old singer made the mistake of lifting his shirt yet again to show off his impressive abs while giving off overly serious model looks.

The Believe singer didn't seem to be in the best mood either as he failed to crack a smile.

At one point he touched his forehead as if he was tired or had a headache.

But considering the long flight from Los Angeles, the Baby hit maker may have just been a bit jet lagged.

The Canadian wonder looked in great shape in his fashionable beige collared shirt, which had its snaps open and with the sleeves rolled up to the elbows. 

Underneath was a plain white T-shirt and when he lifted it, he showed off black Calvin Klein boxers.

He completed his outfits with black slacks and black boots.

Moody man: The star appeared to be channelling iconic Hollywood actor James dean 

His hair was heavily styled with a lot of gel to hold it in place.

Mascara and a trace of lipstick could also be seen on the ex-boyfriend of Selena Gomez.

He was joined by Kendall Jenner, who also represents the line. 

The 19-year-old beauty was at first laughed at when she entered the fiercely competitive modeling world.

But Kendall proved that she is perfectly suited to walk the catwalk and is already on her way to supermodel status.

The Keeping Up With The Kardashians star looked stunning as she posed in an oatmeal crop top and tight black leather miniskirt.

Black heels added even more length to her legs.

After steaming up billboards worldwide, the pair joined forces at the event, each taking their turn to walk the carpet and stop for photographs.

They later did cartwheels on the carpet. Earlier they posed side by side for an Instagram shot.

They have been rumoured to be dating, but neither has confirmed this. He also has been spending time with Hailey Baldwin.

Of course, Justin cannot take all the credit for knowing exactly what pose to pull.

Pulling up one's shirt to reveal chiselled abs and your Calvin Klein underwear was the iconic signature move of Mark Wahlberg.

Now a big time actor, back in the Nineties the star was a musclebound heartthrob and rapper when he was named the face of the designer's underwear collection.

In Mark's day - then known as Marky Mark - his Kendall was Kate Moss.

But 20 years on, the newbies were really stepping it up a notch with their pose off turning physical - turning into a cartwheel competition.

Despite running the risk of showing off her Calvins without meaning to, Kendall busted out the gymnastic move - with Justin following suit - in the middle of the red carpet.  

Getting a little help: Earlier in the day, the star posted a picture of himself and a stylist trying out looks with two racks of clothes behind him

Justin also picked a black T-shirt over a short sleeve sweater which he wore in an impromptu shoot with Kendall just before their appearance.

He seemed to be in a looser mood at that point. 

Surprise: Of course, while he may have been giving Kendall a run for her modelling money, at heart the star is a singer so surprised the waiting crowd with a performance
