Wedding bells are ringing! Following this summer's 'The Materialists,' Celine Song is attached to a buzzy new sequel! The filmmaker has been tapped to write a sequel to Sony's 'My Best Friend’s Wedding.' The film would follow the 1997 classic starring Julia Roberts and Dermot Mulroney as Julianne and Michael, a pair of best friends who made a pact that if they were still single at age 28, they would get married.
