The 38-year-old, who has two-year-old daughter Aviana with fiance Darren Le Gallo, says she still views herself as the "poor girl from Colorado" and she is always shocked when people stop her in the street, reported The Guardian online.
"I still think I'm like the poor girl from Colorado who worked three jobs to buy a car. That is still my mentality, so I will be walking down the street, and I forget what I do and who I am," Adams said.
"Someone will come up to me and say hi, and I'm thinking, I must know you, and I realise that, no, I don't know them and they don't know me. At all," she added.
Adams will be next seen playing Lois Lane in "Man of Steel", a reboot of the Superman film series.
