Donnie Wahlberg Spills Details About NKOTB's First Ever Convention, BLOCKCON

New Kids on the Block singer Donnie Wahlberg shares that the band has performed nearly everywhere, but they've never done a convention—until now. 

"We actually have our first ever convention in two days, it's called BLOCKCON. It's in Rosemont, Illinois. We've never done a convention—and we have 4,000 Blockheads coming," Donnie says.  

"We've done cruises, birthday parties—we've even done prisons in the early days. We've performed everywhere, but we've never done a convention. We're going to try to give everything that we can to our fans for the 3 days that they're here," he adds.
