The newly signed Chelsea striker spent last season on loan at St James' Park but returned to QPR in the summer.
Late in August, however, the Frenchman swapped Loftus Road for Stamford Bridge.
That was not before he rejected an approach to join the Magpies on a permanent deal, though, according to QPR owner Fernandes.
Remy was reported to have rejected Newcastle last month and Fernandes has now confirmed that the 27-year-old did so - while with the Malaysian at the time.
“Loic was having dinner in my house in Chester Square to renew his contract,” Fernandes told the London Evening Standard.
“He is very close to me. He was loyal. He had turned down many clubs - Newcastle right in front of me. Newcastle on paper is a better club than us, a lot of French players there, bigger fan base.
"Then a phone call came from Chelsea, I think [manager Jose] Mourinho. There was a face change in Loic.”
Remy had also been heavily linked with a move to Liverpool earlier in the summer, although the club later pulled out of the deal, citing that the Frenchman had failed his medical.
With Diego Costa currently out injured, 27-year-old Remy could feature for the Blues in their next Premier League clash against Swansea City.
QPR, meanwhile, travel to Old Trafford to face Manchester United, with Alan Pardew's men facing Southampton.
