It’s already been a whirlwind year for Hilary Duff
. On top of playing doting mom
to adorable son Luca
, 2, the singer is hard at work on a new album (her frst in five years!), having announced her separation
from—and possible reconciliation
with—husband of three years Mike Comrie
, 33. So how is it that fans of the former child star, now 26, still can’t perceive her as an adult? OK! caught up with Hilary at the iHeartRadio Music Awards, where she opened up about the difficulty of shedding her Disney alter ego.
