HOUSTON, Texas -- Kanye West is already in Houston before his Lakewood Church visit, and one of his stops on Friday is jail.
The rap icon-turned-gospel musician visited inmates at the Harris County Jail, the county's sheriff's office said.
West and a choir performed for the inmates.
The "Jesus Walks" rapper is scheduled to meet with Pastor Joel Osteen and his Lakewood Church congregation on Sunday.
West is expected to appear for the Lakewood service at 11 a.m. for a conversation. Later that night at 7 p.m., West is holding his "Sunday Service" performance inside the church.
An e-ticket obtained through ticketmaster.com is required to be inside during West's appearances.
