The couple, who reportedly planned to involve their four children in their special day, are planning to host the celebration in the future.
Robbie, whose parents Jan and Pete were reportedly also planning to travel to the U.S, said his milestone anniversary is “more momentous” than having record sales or winning a Brit award.
“It is more important than that and bigger that I have actually achieved that and been a good boy and a good husband,” the singer said, before adding to The Mirror: “So am I looking forward to it? Nah. When it arrives will I enjoy that moment? Yes, I will.”
Robbie praised Ayda for being a source of stability throughout their relationship and said having a family is “a different level”.
