Former ‘X Factor’ judge Rita Ora was “honoured” to have been chosen to perform at the vigil for Mother Teresa's canonisation in Rome on Sunday night. Ora sang ‘What Child Is This’ during the ceremony which took place at the Papal Basilica of St Paul ahead of Mother Teresa being made a saint by Pope Francis.

While Ora might have seemed an unlikely choice for some, it is thought the singer was chosen because she had been born in Kosovo and Mother Teresa herself had been born in a Kosovan territory. Ora brought her family along with her to watch the performance, on what was surely the biggest night of her career so far.

On stage the 25-year-old said: “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 united all mankind without any discrimination, based only on the power of faith and love. The concert and your presence shows it better than anything else.

"Our concert is a journey, an itinerary, an expression of gratitude through music,” she added. “This can be summarised by one quote of Mother Teresa herself: 'It is only love that will save the world’.”

Singing 'What Child Is This?' to celebrate her life and legacy will be a moment I cherish forever.”
