Thomas and his wife Marisol at the 2010 Tribeca Film Festival.
A mutual friend introduced him to model Marisol Maldonado at an afterparty in Montreal in late 1997. They both claim it was love at first sight. Thomas said that, "I knew the second I kissed her that I would never, ever kiss another person." As he was in the midst of an international tour, their initial courtship was via phone. Maldonado was at first reluctant to date Thomas, unsure if she could handle being the wife of a rock star. When he returned to the United States, they went on their first date, to a music festival in Boston. That night, he told her he would marry her, and a month later he proposed. They were married on October 2, 1999, at manager Michael Lippman's ranch in California. Their wedding was broadcast on ABC's Celebrity Weddings in Style.
Thomas has a son from a previous relationship, Maison Eudy, born on July 10, 1998.
Thomas claims that he is sometimes mistaken for television writer Rob Thomas, and vice versa. A conversation between the two men on this subject led to Thomas agreeing to perform a musical number as himself on the TV show iZombie, penned by his namesake.
Charity work
The Thomases are committed animal lovers and supporters of animal charities. Thomas and his wife have established the P Sidewalk Angels Foundation, a non-profit organization created to help needy people in and around America's big cities by partnering with various charities to assist people who cannot afford medical care, and animals that have been abandoned or abused.
Political views
Politically, Thomas considers himself a "fairly liberal guy". He is a strong supporter of gay rights and wrote a piece in favor of legalizing same-sex marriage. He closed the article by writing, "Each of us has a short ride on this earth and as long as we stay in our lane, and don't affect someone else's ride, we should be allowed to drive as we see fit."
In 2007, Thomas was asked his opinions about Michael Vick's sentencing in the 2007 dogfighting scandal. Thomas laughed and responded, "Did he get the chair? *laughs* Did he get the chair?" Thomas then nonchalantly added, "They should have just, like, publicly hung him up."
