Justin Bieber looked like he was raring to go when he arrived at the Hot 99.5 Jingle Ball in Washington on Tuesday.
The teen popstar 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, the Daily Mail reported.
Wearing sunglasses, he 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.
He 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. (ANI)
