Other sites, such as BSBMillennium.com, (not including certain merchandising outfits) are unofficial in spite of any claims that they may make to the contrary. If the site is not listed above then it is not official.
Backstreet Boys~Millennium~ is not an official site (although it would be cool!) and the opinions expressed on this site are those of the webmaster and the fans of the Backstreet Boys, but not those of the Backstreet Boys, their management or their record company.
