The Scottish Sun says QPR and Norwich City have both tabled £4million bids for the striker which have been booted out by club bosses.
But Lennon - whose team turned in another dismal display - was forced to admit Hooper's days at Parkhead are all but OVER.
He said: "There has been interest in Gary from two clubs, QPR and Norwich, and I think that will rumble on for a week or so.
"Can I convince him to stay? It's a difficult one. He's not featured much for us this pre-season. He's got a bit of catching up to do and I don't know where his mind is at the minute.
"I've not had the chance to speak to him yet but it could be difficult for us to keep him."
