Before Justin Bieber and the Jonas Brothers, it was the Backstreet Boys and the New Kids on the Block that were making the ladies swoon.

Not only have they combined their star power for an American tour — but they released an original track together! The song popped up on Billboard this morning and it’s called “Don’t Turn Off the Lights.” In addition to their wildly popular tour, the boy bands have also made headlines this year for their personal lives as well.

NKOTB Jonathan Knight revealed in January that he was gay after teen star Tiffany said she dated a New Kid in the 90s that turned out to be a homosexual. “I have lived my life very openly and have never hidden the fact that I am gay!” Knight said in a statement.

Meanwhile, it was reported earlier this year that BSB member AJ McLean entered rehab as well as Nick Carter’s younger brother Aaron Carter
