A little boy cried when he found his parents' wedding photo, thinking his father was with another woman other than his mum.

The toddler, named Porsche, was curiously browsing the family's photo albums when he reached the pages containing old pictures before he was born in Bangkok, Thailand, on April 20.

But the youngster turned confused and questioned his dad Kanda Thanyacharoen, upon seeing him looking sweet and happy with an unfamiliar face - who was actually her mother when she was younger.

Footage shows the adorable boy bawling his eyes out while pointing at the woman in the picture and interrogating his father about her.

Porsche's mum Mae Som later explained to him that she was the woman in the picture, although they look a bit different years later.
