The whole family was delighted with the arrival.
Gigi's dad Mohamed, 71, penned a handwritten note that read: "Hello little grandchild, it is me, my heart as happy as can be. I wish for you the sun and the moon, I wish for you a happy time.
"Know that Grandpa's always near, I'd do anything, anything for you, my dear.
