The image saw her neighbour with an impressive looking cake – a gift for her and her two children with Derek: Darcey, 15, and 11-year-old Billy.
Kate wrote alongside: “#happyeaster everyone – so hard that it’s the second we’ve lived through in lockdown/restrictions.
“And of course, our second without Derek home with us.”
She went on to share a positive message with users, saying she was thankful he was “still here”.
Kate wrote: “But he is still here, so we have so much to give thanks for and there are lots to hope for, isn’t there?
“Our day started with sun shining and our wonderful neighbour, who we call ‘Cakesuzy’, bringing round the most amazing #easter cake ever she had made herself!”(sic)
