JULIA & DERMOT

Friends forever! Friendship has stood the test of time for Julia Roberts and Dermot Mulroney, 16 years after costarring in 1997's blockbuster rom-com My Best Friend's Wedding. The inseparable pair walked the red carpet together at the Toronto International Film Festival, where they feted the Sept. 9 premiere of their upcoming drama August: Osage County.
