Dick Van Dyke’s wife has opened up about her 46-year age gap with her husband, saying she does not think relationships between people who are the same age “last”.

Arlene Silver, 53, said it was “eerie” how well the relationship with Van Dyke, 99, “works”.

Relationships for celebrities and others in the public eye can often be something of a challenge.

But actor Van Dyke, who aged 99 can still apparently still sing the song “Supercalifragilisticexpialidocious” without making a single mistake, has revealed what works for him and his wife.

Speaking of his marriage of 13 years to Silver, herself an actor and producer, he said: “Everybody said it wouldn’t work.”

His wife added: “I mean it’s like eerie how well it works. People the same age don’t last.”
