Backstreet's Back...Again! The '90s fangirl that lives in all of us was ecstatic when the best boy band ever, Backstreet Boys, announced they were heading to Vegas for a residency à la Britney Spears. It was about to come to an end on July 1, but low and behold, they went and announced they'd be there through 2018. They have shows this November and then some in the beginning of the new year. Now, while there are a million and one things that went through all of our minds when this was announced, these are the most common things that went through fans' minds when it came to Backstreet Boys Vegas residency extension.
