Mariana talking about herself:

"I was born in Jalisco on October 30, 1991, in a very big family with 5 other brothers and sisters, we moved to León Guanajuato with a very short age.

I am 1.78 mts and with 20 years old I participated in Miss Mexico’s contest. Before this I was studying 3rd semester of a Tourism Administration degree.

I participated in the state contest of Nuestra Belleza Guanajuato, after that I represented my state in the national contest of Nuestra Belleza Mexico 2011. So I won the pride to represent Mexico in Miss World 2012.

After winning I moved to Mexico City to start the one year preparation that the National Organization gives me to be the best, and have the greatest participation in an international level.

I also had some social and altruist activities in order stay near to the Mexican people".
