Lennon has a long association with the Scottish giants, having won 11 trophies with the club as a player and five more as a manager, spending a total of 11 years at the club.
Speaking to 'BBC Scotland', the former Bolton boss explained that returning to hos former stomping ground with be an emotional occasion.
"Celtic were a huge part of my life and most of the country know that," he explained.
"The club meant a lot to me, but this is a different chapter in my career now and it is one I am enjoying very much."
"We have also got a semi-final at Hampden against them to look forward to next month, so it will be emotional in many aspects, but I have to be professional as well."
Despite his affinity with the Glasgow-based club, Lennon would no doubt love to get one over on his former side, though he admits that it will be a tough ask to do so.
"It would be long odds on that the way Celtic are playing as they have found a groove," admitted Lennon.
"It was another great win against Rangers and they are an exceptionally good team, as they proved again at Ibrox.
"The good thing is there is no pressure on us when we go to Celtic Park, but I want us to go there and make sure we compete.
"We want to perform the best we can in that game and you never know as there is good attacking intent in the team.
"But we are playing the champions, so it is going to be very difficult."
