Well if you didn't know, he did and it was such a sad time for BSB fans back in 2006. He apparently left the group to pursue other dreams, like acting and starting a family. This was what he said about him leaving the group:
"After 13 years of what can only be described as a dream come true, I have decided that it is time to leave the Backstreet Boys. It was a very tough decision for me but one that was necessary in order to move on with the next chapter of my life. Howard, Brian, Alex and Nick will always be my little brothers and have my utmost love and support. I would like to thank the Backstreet fans for all the beautiful memories we have shared together and look forward to including you in the next phase of my life. I wish my brothers continued success and look forward to their new album."

Actually to be honest, I didn't know he left until I was up to date with their latest music two years ago. Yes they are still around :D and my reaction? Mmm, I kinda wasn't surprised but at the same time I thought, 'Backstreet Boys will never be the same without him :( ' but yeah, it is pretty sad that he's no longer with the group full time :(.
