It’s official: Sandra Bullock wants out of her nearly five-year marriage to Jesse James.
“Yes, I have filed for divorce,” the actress, 45, tells PEOPLE in the latest issue, in which she also reveals she has adopted a son, 3½-month-old Louis.
A rep for Bullock confirms the star filed legal papers seeking to end her marriage, but declines to specify in what jurisdiction they are filed. Says Bullock of her decision to divorce: “I’m sad and I am scared.”
It was a cheating scandal that rocked the couple’s marriage, with several women claiming to have had illicit affairs with James, 41.
