They fell out famously after his stint on The X Factor, which led Simon to drop him from his music label… but now it looks like James Arthur is making a comeback.
James could very well resurface with a major bang now that Simon has signed him BACK onto Syco this week.
After topping the iTunes charts with Say You Won't Let Me Go and The Truth, the 28-year-old was signed right back up by the music mogul.
A source told The Sun: "Over the last few years James has kept in touch with Simon.
"Simon has always thought James is a real talent but as soon as he heard the record he made up his mind to re-sign him.
"James has grown up a lot and realises he made mistakes in the past. Simon knows this."
It'll be interesting to see how this turns out.
