Watch Mark Wahlberg Reunite With New Kids on the Block for the First Time in 20 Years

Mark Wahlberg

The 'Ted 2' actor joined his former bandmates onstage at Madison Square Garden in New York City.

Mark Wahlberg's promotional schedule for Ted 2 includes TV spots, interviews, red-carpet premieres and, surprisingly, an onstage New Kids on the Block reunion — for the first time in 20 years.

The actor and original member of the group (who left very early on for a solo career) stopped by Madison Square Garden on Monday night for the band's second show at the New York City venue.

The band currently is touring with TLC and Nelly as part of its arena jaunt, The Main Event. The evening also included special guests 50 Cent (who brought Wahlberg onstage, as seen in the video below) and Biz Markie.
