Courteney Cox is reportedly planning on adopting with husband David Arquette in a bid to save their marriage.

The couple - who recently spent New Year in Mexico with best Friend Jennifer Aniston - are said to be eager to adopt after several failed attempts conceive a second child.

A source tells the National Enquirer, "David wants a sibling for Coco, but Courteney's reached a point where she feels it's hopeless to keep trying to get pregnant.

"They love each other very much, but with Courteney's intense work schedule and her resisting adoption, David started acting out, going out nights without her.

"But now that Courteney's given the Okay to adopting a brother or sister for Coco, David has agreed to scale back on nights out and be more accommodating to Jennifer Aniston when she's on the scene.

"It's a win-win scenario for Courteney and David."

Courteney struggled to fall pregnant before she and David finally concieved four-year-old Coco.
