This is the heartwarming moment children prepared a surprise birthday cake with a chain of money for their mother's 60th birthday party.

In the video, Juliet Farrel is seen tearing into the cake as her seven children watch in in Mandaluyong City in Manila, the Philippines, on July 31.

Daughter, Anne, said that her mother was expecting a simple celebration so she was surprised when the table was full of food and each of the children had put forward 1,000 pesos for the money chain hidden in the cake.

Anne said: "I thank God because he gave us a kind and loving mother who is willing to sacrifice everything for her children and grandchildren. ''Moreover, I am happy because our mother is still strong and healthy.''
