Guitar hero Carlos Santana and wife Deborah have filed for divorce after 34 years, according to court docs.

Deborah filed for divorce in Marin County Superior Court on Oct. 19, citing irreconcilable differences, and she's alleged in the past that Carlos has been unfaithful. Even Carlos has admitted mistakes; he has said, "I sincerely apologized to her and to my kids when I wasn't in my right mind and did something hurtful."

The Santanas have three children, ages 17, 22 and 23.
