Pop singer John Newman, a frequent collaborator of the likes of Calvin Harris and Rudimental, is reportedly due to undergo brain surgery to remove a tumour next year.

The 26-year-old was initially diagnosed with a benign brain tumour in 2012 and had it removed, but it has returned - although it is benign. It's believed that he'll take time out next year to have it removed and will then undergo radiotherapy after 'cancerous cells' were found.

A source told The Sun: "John’s brain tumour is back. He’s known about it for a while but has kept it a closely guarded secret, confiding only in those closest to him – his mum, brother and few loyal members of his family.

After the operation, he’ll need some radiotherapy so there’s talks of him taking a few months off to get the job done and convalesce. Although he’s trying to remain as positive as possible it’s a really emotionally draining time for poor John."

Newman is best known for his track 'Love Me Again', as well as featuring on Rudimental's 'Feel the Love' and 'Not Giving In'. More recently, he collaborated with Calvin Harris on the song 'Olé'.
