New Kids on the Block by Ron Galella, Ltd./WireImage.com
They're back! 1980s boy band New Kids on the Block is reuniting, and will release a new album and go on tour. The announcement comes 20 years after the Boston-based fivesome scored big with their multi-platinum album, Hanging Tough.

Band member Donnie Wahlberg, 38, told the Boston Herald he was onboard with the reunion when the group decided to write new music. "We absolutely will [also] do the old songs for sure," he added.

Joey McIntyre, brothers Jordan and Jonathan Knight, and Danny Wood round out the quintet, which in its heyday sold 70 million albums before breaking up in 1994. - J.R. Whalen
