In case you haven't been paying attention, New Kids on the Block is making a major comeback. The iconic '90s group has been on their Main Event Tour, and this week, they played Madison Square Garden. What started off as a typical show became kind of a big deal when special guest 50 Cent called Mark Wahlberg to the stage. The former NKOTB member was in town promoting Ted 2 [1], and fans went insane when he showed up. Check out the pictures and the video below!
