The Mirror Mirror actress explained to Seventeen magazine that her full brows helped to distinguish her from other stars.
"It used to bother me - having bigger, fuller brows. I even plucked them once so I'd fit in, but I hated them and couldn't wait for them to grow back," Collins recalled.
The actress went on to say: "Now I embrace them. I've realised the quirky things that make you different are what make you beautiful."
Collins also revealed that being the daughter of music icon Phil Collins can only get her so far in the entertainment industry.
"My last name may have opened doors, but I have to keep them open," she insisted.
Collins co-stars with Julia Roberts in Mirror Mirror, opening on March 30 in the US and on April 2 in the UK.
