Courteney Cox and Johnny McDaid are reportedly discussing adopting a baby together.

The couple, who are rumoured to be engaged, are eager to start a family together as the Snow Patrol pianist has bonded with the actress' nine-year-old daughter Coco, her child from her previous marriage to David Arquette.

The pair think it would be great to give a disadvantaged youngster a new life and give Coco a sister.

A source told Life & Style Weekly magazine: ''Courteney proposed the idea of adopting a child to Johnny after their family vacation to Italy in February. And Johnny is all for it. He's in love with the idea of growing a family with her.''

Courteney, 49, and Johnny, 37, sparked speculation they are engaged after the former 'Friends' star was spotted wearing a huge diamond ring on her engagement finger as she strolled through Los Angeles International Airport (LAX) earlier this month.

Pals are predicting the couple will tie the knot before her Courteney's pal Jennifer Aniston marries her fiancé Justin Theroux.

Another source said: ''She can't wait to marry him. I know she doesn't want to wait very long because she's so, so happy. She will probably be married before Jen.''
