It seems Justin Bieber was raring to go when he arrived at the Hot 99.5 Jingle Ball in Washington on Tuesday.
The pop star was already in performance mode as he walked the red carpet and started pulling some moves for the cameras.
The 18-year-old grabbed his crotch as he struck a pose – a gesture the Michael Jackson fan often makes onstage.
Justin, who covered his face with sunglasses, also flipped the 'peace' sign as he prepared to make his way inside.
His energetic mood was continued when it was time to perform, and Beliebers in the crowd would have been delighted when the star flashed his abs during one song.
He checked himself out as he lifted up his top, looking pleased with what he saw.
The Boyfriend hit-maker had been dressed casually when he arrived for the evening.
Justin was sporting a grey hoodie over a cat-printed T-shirt, along with baggy jeans, high-top trainers and a yellow UCLA trucker hat.
He then changed into his favourite drop-crotch trousers and black leather tank top, fingerless gloves and trainers before taking the stage.
The audience were treated to a veritable feast of performances by a host of singers, including Enrique Iglesias and Austin Mahone.
And the crowd got particularly enthusiastic when a shirtless Flo Rida made his way through a sea of his lively fans.
Cher Lloyd also performed at the festive bash, looking lovely in a patterned shift dress.
On first glance it appeared as though her grey and brown frock was demure, however its sides were in fact made up of sexy sheer black panels.
Also in attendance were a very casually dressed Ed Sheeran, Ke$ha, sporting a sheer black blouse, striped trousers and a blazer, and Gangnam Style singer PSY.
