A mother appeared to be unhappy when her children surprised her with a roasted pig on her birthday.

Mum Adelaida Comahig, 60, knew she was having a party on her special day but was unaware her family had cooked an entire pig to celebrate in Lanao del Norte, the Philippines.

Footage shows Adelaida emerging from the kitchen into the living room, where she was greeted by the grand feast.

Her eyes widened in shock, but after a few moments she approached her children with a smile.

Son Jovert said: 'It was the first time we ever had a lechon at home. She could not believe it because it can be expensive.

'She might have looked unhappy, but in reality she was delighted with our surprise.'

Lechon is a traditional Filipino dish consisting of a whole pig that is roasted over charcoal until the skin becomes crispy and golden brown. It is often the centerpiece of large gatherings.

It came from the Spanish word for roasted pig which was introduced during the colonial period but has since become one of the Philippines' most beloved dishes.
