It’s a major achievement in an artist life when they sell out the famous Madison Square Garden in New York CIty. Justin Bieber is no stranger to that achievement, selling out the arena in 2010. The “Boyfriend” singer, who has been shaking the world up has sold out Madison Square again, twice! Guess how long it took him to do it . . . 30 seconds . . . two nights in 30 seconds! That is incredible, Bieber is definetly unstoppable! How long did it take the Biebs to sell out his entire, “Believer” North American Tour . . . one hour! Bieber kicks of his tour in late September and visits over 45 cities across the country. His protege, Carly Rae Jepsen will be joining him, singing her summer hit, “Call Me Maybe”.
