Justin Bieber Learns Spanish Ahead of Mega Concert in Mexico City: 250,000 Fans Expected

Justin Bieber arrived to Mexico City on Monday to perform at a mega free concert tonight and upon his arrival the pop star was getting cultural and learning Spanish.

Bieber said at a press conference today that his favorite words in Spanish are "hola," (hello) "te amo," "te quiero," (I love you) and "amor" (love) and he reportedly learnt to say "Jefe" (Boss) with reporters today, according to local newspaper El Universal.

The pop singer might well become the "Boss." Bieber told reporters 250,000 people are expected to attend the free gig at Mexico City's main plaza "The Zocalo."

At that number, he could make history and become the new record holder for the largest crowd at the popular venue.

Currently the record for the largest audience for a free concert at The Zocalo belongs to Mexican singer Vicente Fernandez with 217,000 people. Shakira is second with 210,000.

Local authorities estimated 200,000 people, mainly young girls from all across the nation, would come to see Bieber perform.

Hundreds of Bieber fans were camping out in the city center to seek to be closest to the open-air concert stage, according to media reports.

Mexico's government has set up seven giant screens located near the main plaza to stream the concert for those who couldn't make it to see him on stage.

Bieber is expected to perform with Canadian singer Carly Rae Jeepsen.
