AMANDA Seyfried thinks a break-up is like mourning a death. The Red Riding Hood actress insists she didnt worry about going through her split with her Mamma Mia costar in the public eye because it was already so difficult to deal with. It didnt really matter to me that it was public. Being seen out with Dom, or having things written about me or the break-up didnt really bother me, she said. SS
