Surprise! Mark Wahlberg Joins NKOTB On Stage At Madison Square Garden

New Kids on the Block fans got a special treat last night, when Mark Wahlberg joined the original '90s boy band on stage for a surprise appearance at their Madison Square Garden concert. While NKOTB member Donnie Wahlberg performed "Good Vibrations" — yes, the one a young (and spectacularly shirtless) Marky Mark himself gave us back in 1991 — rapper 50 Cent told the jam-packed crowd that he felt "like we have some good vibrations here tonight." And without further ado, Mark Wahlberg walked on stage to near deafening roars, joining his brother and the rest of NKOTB for the first time in more than 20 years. Talk about the right stuff. Wahlberg wasn't the only special guest to grace the stage at the sold-out show: Rappers Biz Markie and 50 Cent hit the NYC stage to perform "Just a Friend" and "In Da Club." Fellow '90s icons Nelly and TLC are also along for every stop of NKOTB's nostalgia-inducing Main Event Tour, which kicked off in Las Vegas last month. Next up? Boston and Buffalo. (And with Bean Town also being the boys' hometown, we have our fingers crossed for some more fun surprise appearances there tonight.) But for those of you not able to make it in person to the concert of your '90s dreams, we offer you this small gift: New Kids on the Block's 1991 Super Bowl Halftime Show. You're welcome.
