The former Friends star and Snow Patrol guitarist Johnny had been engaged and planning to wed soon, but reports from the US claim that they've now ended their relationship.
Neither Courteney nor Johnny have confirmed this yet.
A source told TMZ that the couple's split was amicable and mutual and that Johnny's now moved out of the home they shared in Los Angeles and returned to the UK.
Courteney, 51, and Johnny, 39, were first linked in 2013 when they were pictured arriving together to Jennifer Aniston's annual holiday party. They announced their engagement in June 2014 - after Johnny asked permission from Courteney's daughter Coco.
