COVER STORY: Sandra Bullock — A Baby at 47!

Sandra Bullock never intended to become a single parent. For years, friends say, she tried in vain to conceive with her biker mogul ex-husband, Jesse James. Finally, the couple initiated the adoption of her now-19-month-old son, Louis — and then everything went horribly wrong. But now, everything seems to be going right, as OK! reveals in the new issue, on sale everywhere Thursday!

During her finest hour — winning the Oscar for The Blind Side in 2009 — Sandra saw her marriage explode over Jesse’s infidelity, leaving her to raise Louis alone.

“At first she was devastated, of course,” a pal tells OK!. “But once the adoption went through, she was over the moon. She’s never been happier than she has been since Louis entered her life.”

And now Sandra’s life is getting exponentially better. As her decade-long friendship with onetime co-star (in The Proposal) Ryan Reynolds ripens into a full-blown romance, the actress may be on the verge of realizing another dream.
