Karisma Kapoor posted this picture of dad Randhir Kapoor cutting the special cake that read, "Happy Birthday Nanu".

Veteran actor Randhir Kapoor, father of Karisma and Kareena Kapoor Khan celebrated his 71st birthday on Thursday. What really melted everyone's hearts was the birthday cake! It wasn't like any other normal high-protein and gluten-free cake but something extremely precious written on it. The cake had Randhir's grandchildren - Samaira and Kiaan (Karisma's children) and Taimur Ali Khan's name designed on it with a beautiful birthday wish - "Happy Birthday Nanu". Karisma took to her Instagram account to share the pictures from the intimate family gathering.
