NEW YORK -- People magazine has named Sandra Bullock as the "World's Most Beautiful Woman" for 2015.

The 50-year-old actress, who voices a supervillain in the upcoming movie "Minions," tops the magazine's list, announced Wednesday.

Commenting on being selected for this year's cover, Bullock says she just laughed when she heard about the honour. "No, really. I just said, 'That's ridiculous,"' she tells the magazine. "I've told no one."

Bullock, who won an Oscar for "The Blind Side," says she's found beauty in her role as mother to her 5-year-old son, Louis.
