Ashley Olsen has decided to remain with her twin sister, Mary-Kate, instead of going on a planned trip to Australia to promote the opening of the siblings' latest movie adventure "New York Minute," reports the AP.
Ashley Olsen is a year older than her sister. 
The article states that they are twins, and therefor the same age. I think the system doesn't understand what words mean all the time.
