Since rumors began circulating of [article id="1634234"]Jesse James' alleged infidelities[/article], Oscar-winner Sandra Bullock has remained on the down-low, leaving fans wondering what her next move might be. In the new issue of People, out this week, Bullock revealed just what those plans are.

The actress announced that she has filed from divorce from her TV personality husband and is a new mom to an adopted boy. "Yes, I have filed for divorce," she told People, adding, "I'm sad and I am scared." Her decision to leave James came about after several women claimed they had affairs with him. Soon after the allegations, James completed a 30-day stay in an unspecified rehab program to deal with [article id="1635119"]"personal issues."[/article]

Bullock is also now a mom to a 3-1/2-month-old boy, born in New Orleans, who she named Louis Bardo Bullock. "It's like he's always been a part of our lives," she said.

The actress said that she and James started the adoption process four years ago and brought the baby home in January, but decided to keep the news to themselves until after the Oscars, where she won Best Actress for her work in "The Blind Side." She added that her friends and family, including James' three kids, helped ensure no one would find out about the baby until they were ready.

While Bullock has remained pretty mum about her marriage and the baby since the infidelity allegations, she did release a statement regarding [article id="1635526"]rumors that she and James had a sex tape[/article], denying they were true. James also confirmed there was no sex tape. "There is no sex tape," she said in a statement. "There never has been one and there never will be one."
