The heartbreaking news comes just over two years after Félicité and Louis’ mother, Johannah Deakin, lost her long battle with leukaemia. It was exactly one week ago that the 27-year-old singer released an emotional new song about his mother’s death called ‘Two of Us’.

In Louis’ tribute song, he sings directly to Johannah, telling her how much he misses her and how he’s living his life for the “two of us.”

“You’ll never know how much I miss you/The day that they took you, I wish it was me instead. But you once told me don’t give up/You can do it day by day/And diamonds they don’t turn to dust or fade away.”

In an interview with Radio 1 Newsbeat, Louis discussed how he used to call upon his mother for advice.

“It was something I needed to get off my chest,” he said. “I used to lean on my mum for a lot of things – anytime I needed advice on something she would be the first call I made.”

Thoughts and prayers are with the family at this tragic time.
