She may be PEOPLE's 2015 World's Most Beautiful Woman, but Sandra Bullock doesn't take herself too seriously when it comes to her appearance.
Despite being in "princess mode" while shooting for this year's cover story, Bullock, 50, insists she just laughed when she heard about the honor. "No, really. I just said, 'That's ridiculous,' " she tells PEOPLE. "I've told no one."
Instead the Oscar winner, who voices a supervillain in the upcoming movie Minions, has found beauty in her role as mom to her 5-year-old son, Louis, adding that their life together is a constant reminder of what's important.
