JULIA & DERMOT

Friends forever! Friendship has stood the test of time for Roberts and 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, 2013, premiere of their drama August: Osage County.
