Music was at the forefront last evening in Las Vegas as LAX Nightclub played host to the official after concert party for the New Kids On The Block. Dressed to the nines, Donnie Wahlberg, Danny Wood, Jordan Knight, Jonathan Knight and Joey McIntyre strutted down the red carpet and into VIP were they basked in a sea of flashing light bulbs. Catering to their screaming fans’ requests, the sizzling boy band made their way to the top of the DJ booth to deliver an electrifying impromptu performance which included songs “Dirty Dancing,” “Single” and “Put it on my Tab” off their new album. After the mini concert, the group retreated to their VIP tables and danced all night long with a large group of friends to the sweet sounds of DJ Hollywood. Earlier in the evening, actor Dennis Haskins, best known for his role as Mr. Belding on Saved By The Bell, took in the sexy scene around him as he mingled with other guests in VIP and took photos with some lucky fans.
