SANDRA BULLOCK

Most Beautiful 2015: When she was named PEOPLE's Most Beautiful Woman last year, the actress simply laughed. "No, really. I just said, 'That's ridiculous,'" she told PEOPLE. What really makes Bullock feel beautiful is her role as mother to her son, Louis. "What is beautiful is the honor of being Louis' mother," she said.
Now: Sandra has her hands full at home – she welcomed a sibling for son Louis this year, daughter Laila, who she adopted. “When I look at Laila, there’s no doubt in my mind that she was supposed to be here,” she told PEOPLE of her daughter.
