Angela Bassett chats with ET's Deidre Behar at the Los Angeles premiere of '9-1-1.' The star is getting ready to be an empty-nester alongside her husband, Courtney B. Vance, as their 18-year-old twins prepare to go to college. They've already toured 26 colleges, and Angela says when the time comes for them to leave, she 'might have to go to therapy.' Plus, Angela also talks about how high the stakes get on season 7 of '9-1-1,' which premieres March 14 on ABC. Source
