Sexy voice.
At one point I thought she sounded just like Emma Watson. Love those sexy British accents. Wish she would've had more lines.

I actually find Emma's hysterical voice very annoying but Rosie's is nice. Cate Blanchett, Rachel Weisz, Audrey Hepburn, and Anna Walton (who not only looks a lot but sounds a lot like Audrey too) are my favorite female Brit accents.
