The former Friends star was snapped doing errands in the sunshine and having lunch with friends on Wednesday (9 September), as she gets ready to tie the knot with Snow Patrol musician Johnny McDaid.
It's no surprise that Ed would be invited to the nuptials, as he's the one who introduced Courteney and Johnny in the first place!
Ed had been staying in the guest house of Courteney's Malibu home and working on music with Johnny when the introduction happened.
And in April he was the one who revealed that Courteney and Johnny's romance had taken the next step: "Things are moving fast. He moved in and judging by the last time I saw them, they couldn't be happier."
They announced their engagement in June.
Courteney told The Sun last month: We are certainly grateful to Ed for introducing us. I can't imagine him not playing something at the wedding. It'll be a musical night."
This will be Courteney's second marriage. She was previously wed to Scream co-star David Arquette, the father of her daughter Coco.
