"I Will Never Let You Down" singer Rita Ora honoured Mother Teresa during the "What Child Is This concert" on Sunday at the Papal Basilica of St. Paul at the Vatican.

The concert was a dedication for Mother Teresa, who was proclaimed as a saint by Pope Francis that night, according to The Daily Mail.

Before giving her heartfelt performance, Ora posted about the event on her Instagram account (@ritaora) and wrote, "Singing 'What Child Is This' to celebrate her life and legacy will be a moment I cherish forever."

Hundreds of priests and dignitaries were present to hear Ora sing. However, Pope Francis did not seem to be among the guests.

Ora was chosen to sing because both she and Mother Teresa were born in Kosovo. Ora was originally from Pristina, which is the capital of Kosovo, but she was forced to move to Britain as a refugee.

Mother Teresa was born in Skopje, which is now the capital of Macedonia. Previously, it was a Kosovan district of the Ottoman Empire.

Before singing, Ora provided this message to the crowd: "Tonight on the eve of the canonisation of Mother Teresa, we, the daughters and sons by blood and soul, are here to honour and express our gratitude to her outstanding life and work dedicated to the poorest people of the world."

"A humble woman managed to unite all mankind without any discrimination, based only on the power of faith and love," she said.

"The concert and your presence shows it better than anything else. Our concert is a journey, an itinerary, an expression of gratitude through music. This can be summarised by one quote of Mother Teresa herself: 'It is only love that will save the world.'"
