A toddler joined airport staff as they sang a happy birthday song to their colleague.

Footage shows two-year-old Tarrah in the middle of the crowd wearing yellow uniforms at the Ninoy Aquino International Airport in Manila, the Philippines, on January 6.

The youngster clapped and sang along with kind strangers she found while waiting for a relative with family at the arrivals area of Terminal 1.

Tarrah was also given a slice of cake by her newfound friends at the airport.

Her mum Precious Mariah Maravilla said: 'We moved to another seat when we heard they were planning a surprise celebration for their colleague. But when we looked back, Tarrah was already there, joining them in the party.'
