Beauty queen wife of Mexico's most wanted drugs lord crosses border to give birth to twins in California

The wife of Mexico's most wanted drug lord has given birth to twin girls at a hospital in northern Los Angeles County, it has been reported.

Emma Coronel, the 22-year-old wife of multibillionaire Joaquin Guzman - who is widely considered the world's wealthiest drug trafficker - freely crossed the border as she has U.S. citizenship.

She arrived in the U.S. in mid-July before delivering her daughters at Antelope Valley Hospital in Lancaster on August 15, reported the LA times.

The former beauty queen returned to Mexico after they were born.

Birth certificates listed Coronel as the mother of the girls, but the spaces for the father's name are blank.

U.S. law enforcement officials, who tracked her movements even before she travelled to Lancaster, told the Times that Coronel was not arrested because there are no charges against her.

Coronel is believed to be the third or fourth wife of Guzman, the 54-year-old multibillionaire head of Mexico's most powerful drug-trafficking gang, the Sinaloa cartel.

The couple married the day she turned 18 at a lavish wedding in the highlands of central Mexico in 2007.
