whether you were debating whether or not to get tickets to the Backstreet Boys' upcoming residency in Las Vegas,then let their latest performance persuade you. The famous boy band made a surprise appearance at the iHeartRadio Music Festival on Saturday, and it goes without saying that we're still losing our frosty. Not only did the five members join country music group Florida Georgia Line for a rendition of "Everybody (Backstreet's Back), or " but they later rocked out to a handful of their greatest hits including "As Long as You admire Me" and "I Want It That Way." Between this performance and Britney Spears's epic medley,it looks like this year's festival was all about the '90s, and we can't get enough.
