(June 23, 2015) – Upping the ante on their second jam-packed night at Madison Square Garden on their Main Event Tour, New Kids On The Block surprised thousands of fans with an appearance by Mark Wahlberg during Donnie Wahlberg’s performance of “Good Vibrations.” Rapper 50 Cent teased the eager crowd at the end of his performance, telling them he felt “like we have some good vibrations here tonight...” leading into Mark’s entrance on stage, which marked the first time he had joined NKOTB on stage in more than 20 years to celebrate their successful two-night run at MSG.

Rappers Biz Markie and 50 Cent also returned to the stage last night to perform “Just a Friend” and “In Da Club” respectively after surprising fans at the packed show for the second night in a row.

The tour has been thrilling fans and earning critical praise across the country since it kicked off May 1 in Las Vegas. Fuse raves that “it was clear that although these men are definitely not new kids anymore, they still have the right stuff” while Dave Holmes of Esquire proclaims, “I’ll be damned if it wasn’t the best time I’ve had at a concert in years.”
