A source tells STAR Magazine, “Sandy found out she was pregnant in October,”

“Sandra has denied the pregnancy to the press, but the source insists that Bullock, 42, is already four months along.

“It has been a hard year but [this baby] has really strengthened their marriage.”

According to the source the couple had been trying to have a baby before they even married in July 2005.

“Having a child has been their primary focus. When it didn’t happen, Sandy was ok- she’s a go with the flow type- but it was like somebody sucker punched Jesse in the gut,” says the source.

Sandra and Jesse plan to raise the baby away from Hollywood, at their home in Austin, Texas.”
