The two clubs have now settled on a fee for the player and, according to reports, Hooper has already agreed terms with the Premier League club and will have a medical at Carrow Road later today.
Hooper is valued at around £4.5m with Celtic looking to sell as he is in the last year of his contract.
Hooper has netted 82 goals in three years for Celtic and came off the bench as they eased into the third qualifying round of the Champions League at the expense of Cliftonville on Tuesday night.
It had looked as if Hooper had all but signed for Championship club QPR with Harry Redknapp talking about how big of an impact he would have at the club.
Redknapp told BBC Radio Scotland: "It looks like it's on its way to being done. Negotiations have gone well.
"He's a finisher. He'll score goals in the Championship; I'm absolutely certain of that.
"He's gone to Celtic; one of the biggest clubs in the world and he's scored goals. He's scored goals in the Champions League.
"He's in the last year of his contract, so it's a good deal for everybody. It's good for Celtic to get the kind of money they are getting and hopefully it will be a great deal for QPR.
"If he can come here and get 25 goals next season, then we will have a real chance of getting out of the division.
"I think Gary is capable of reaching that sort of target.
"We're going to need two strikers and I think they are going to have to weigh in with 50 goals."
However, it now looks like Norwich is going to be his destination where he could set up a brand new striker double act with Dutch international Ricky van Wolfswinkel have already signed from Sporting Lisbon for club-record £8.5million fee.
