Hooper took his season tally to 31 goals with a first-half brace at Hampden and was praised by his boss who also felt the Englishman's strike partner Anthony Stokes was at his best for the Glasgow giants.
"Hooper's a master - absolute master," said Lennon.
"But his partner in crime, Stokes, had probably his best game in a Celtic shirt.
"I had a gut feeling about Stokesy all week, but I didn't realise he was going to play as well as that.
"He showed why he's getting another contract because he's a good player. He's looked better in his last few matches, more consistent and stronger. He looks like he's found a yard of pace.
"And that's all down to the time he had off working really hard during his rehab.
"It was a great all-round team performance."
