His agent Neil Dobias, who originally reported James missing, has confirmed the news.
The singer was reported missing by police earlier today (Saturday 30 August).
Fears grew for the reality TV star, nicknamed Arg, who had not been seen for more than 24 hours.
Police in Redbridge, Essex, launched a man hunt for the missing singer after becoming concerned for his welfare.
James, 26, was last seen at around 3am on Friday morning at his home in Woodford Green, Essex, and had not made any contact with friends or family since his disappearance.
A Metropolitan Police spokesman said at the time: "His family and friends knew him to be at his home address at the time. Obviously he has left home but it is not known where to.
"It is unusual according to his family and his agent."
His spokesperson Neil Dobias issued a statement saying the reality star was due to meet him at the airport in the early hours of Friday morning but didn't show, sparking worry.
James' last tweet was directed to his on-off girlfriend Lydia Bright. "I really miss my old pal @LydiaRoseBright will you hurry up and get back from Italy ASAP! #Needy x."
