Cuba Gooding Jr.'s wife, Sara Kapfer, filed for legal separation Tuesday. The 46-year-old actor and Kapfer are high school sweethearts and have been married for 20 years. The couple have three children together: Spencer, Mason and Piper. Kapfer cited irreconcilable differences as cause for the split. TMZ reports that she requests legal and physical joint custody, and child support will be determined later.
