Actress Saoirse Ronan with her mother Monica at a recent Dublin fashion show. 

Irish star Saoirse Ronan grabbed some girly time with her mother Monica at a Brown Thomas fashion show at the Four Seasons in Dublin on Friday afternoon.  She’ll soon be back on the publicity trail hyping her next movie, How I Live Now, which opens in the U.K. next month and here in November.  Saoirse, 19, plays a young American girl spending a dreamy summer in England that soon turns bad as a 21st century world war breaks out, and she’s got to fight for her life.  She’ll likely be at the Toronto Film Festival this week as the film has been green-lighted for its world premiere at the prestigious annual event.
