Bullocks Joy!!

No one can deny that Sandra Bullock has been through the best and worst of times this year - from winning her first Oscar to enduring the breakup of her marriage.

And now she has some sunshine to her life. Her newborn/ adopted son Louis is the source of that joy.

Bullock reveals exclusively in the new issue of PEOPLE that she is the proud mother of Louis Bardo Bullock, a 3 1/2-month-old boy, born in New Orleans. Bullock, 45, and husband Jesse James, 41, began the adoption process four years ago and brought Louis home in January but decided to keep the news to themselves until after the Oscars.

Then, just ten days after the March 7 Oscars, Bullock and James separated following reports James had cheated. Bullock says she is now adopting as a single parent.

Good for her!
