Justin Bieber

If you thought we'd already hit peak Bieber-fever, don't hold your breath. The Bieberenaissance is upon us. Perennial chart-topper, and former tween-pop laughing stock has reinvented himself as pop-culture's latest libertine, aping fellow chart titan Justin Timberlake's sleek R&B style crooning. The baby-faced Canadian hits Croatia for the first time in November, a date for committed beliebers and Justin newcomers alike.
