Torres has two older brothers (José and Joey) and a younger sister (Jeannette). She finished her studies in Colegio Santa Rosa in Bayamón, Puerto Rico with the intention of going to college to become an orthodontist.

Torres married singer Marc Anthony on May 9, 2000 in Las Vegas. They have two sons, Cristian Anthony Muñiz (5 February 2001) and Ryan Anthony Muñiz (16 August 2003). It was a rocky marriage, and they separated in the summer of 2002. They later reconciled and renewed their vows in a spectacular ceremony which was held in Puerto Rico in December 2002. In 2003, a Miami waitress filed paternity charges against Anthony. Multiple DNA-tests, the last in August 2004, disproved her claims. The couple's final separation was in October 2003. Torres filed for divorce in January 2004.

As the divorce proceeded, Anthony was seen out with actress-singer Jennifer Lopez, a long-time friend whom he had worked with in music videos. They had briefly dated in the late '90s,
