The Bieber may outdraw the Beatle. That's what Mexico City officials are saying as they prepare for Monday's free concert by teen star Justin Bieber.
Paul McCartney's May 10 concert in Mexico City's central plaza attracted some 200,000 people and city Tourism Secretary Carlos Mackinlay says organizers expect "a little more" for the Bieber event.
Officials are planning elaborate security arrangements for the event, with nearly 6,000 police officers, two helicopters, 500 portable toilets and four rings of barriers. Checkpoints will limit the crowd in the plaza to about 80,000, with other fans directed to watch the concert on giant screens erected on neighboring streets.
