The father of Monaco's Princess Charlene insists he will treat her twins "just the same" as his other grandchildren.
Mike Wittstock and his wife Lynette have jetted to Monaco to be close to their 36-year-old daughter ahead of the birth of her first children with husband Prince Albert and though they are excited about their impending arrival, he insists he felt just the same about the other two babies born into his family this year.
Speaking to French publication Point de vue, he said: "Our son Sean, who lives in South Africa, is the father of a 10-month-old child and yesterday it was the first birthday of our granddaughter.
"Now there are two others about to be born, as you know! It's amazing! Our grandchildren come fast and furious. Four in a year.
"I will respect everything required by the protocol, my daughter knows that, but other than that they will be treated in the same way as their cousins."
And despite being born into royalty, the twins will have a savings account opened for them by their grandparents, just as they have done for the other children.
He added: "I have already opened a savings account for their futures and my daughter's children will also have their own, with the same amount in.
"They certainly do not lack funds but I will treat them equally."
Charlene recently spoke of her excitement at the prospect of being a mother.
She said: "The prospect of the upcoming birth is so magical, so powerful. We are full of love, gratitude, as well as a great sense of responsibility.
"I am particularly grateful for the spontaneous love bestowed on me in these special moments. The show of affection for my family, of the totality of the Monegasque people and all our friends."
