The 38-year-old actress revealed she studies the inspirational photos with her styling team, reported Contactmusic.
"It's part of my preparation for major red carpet events. That said, on one occasion a hair stylist made my hair enormous - but rather than freak out, I thought, 'I'm just going to take my big hair out for the night - you work it, girl'," Adams said.
The actress, who is engaged to long-term partner Darren Le Gallo, said her bizarre ritual has enabled her to understand what works and what will photograph well.
