New Kids On The Block Serenades Carrie Underwood At 2015 Nashville Show

New Kids On The Block was on tour back in 2015 and stopped by all the major arenas in the country. While they were in Nashville, one famous country singer made sure she was able to attend because she is such a huge fan.

Carrie Underwood is a huge NKOTB fan it seems, and she couldn’t have been more excited to be at their concert. Not until partway through the concert did anyone even know she was in the audience!

Well, when the boy band found out that she was in attendance, they decided they needed to sing her a song which she has claimed in the past is “her song.” That would be “Single” a duet with Ne-Yo from their 2008 album, The Block.

It seems the feeling is mutual, seeing as just two years later, Donnie Wahlberg brought out Underwood on stage to sing “Happy Birthday” to members Danny Wood and Jordan Knight.

The song “Single” definitely brought out the teenage girl in Carrie as she swayed and sang along with everyone in the audience, then gushing about her experience on Twitter:

How exciting! Check out the video below.
