Linfield beat Portadown 2-1 at Windsor Park to retain their Premiership crown.
Philip Lowry scored the opening goal in the 70th minute, running onto a through ball from Robert Garrett, before finishing coolly past Tuda Murphy.
Richard Lecky looked to have postponed the Blues' title celebrations when he scored on 85, but Jamie Mulgrew slotted home the winner two minutes from time.
For the Blues, it is their 51st domestic league championship success and their sixth in seven years.
It is boss David Jeffrey's ninth league success as manager of the south Belfast club.
Peter Thompson fired over the bar early on and Jamie Mulgrew also had chances for Linfield, while Alan Blayney saved a first-half Matthew Brown effort.
Lecky's equaliser was a fine finish, while Mulgrew took advantage of a defensive slip up to round goalkeeper Tuda Murphy and fire home and spark the celebrations among the home fans.
After the game, Jeffrey described the club's title victory as "the best one yet".
"Portadown played well in the first half, but we were better in the second half and plugged away, showing desire and determination.
"I am ecstatic - what an emphatic way to win a league title.
"It is a tremendous feat and the players deserve so much credit - expectation levels are so high and the pressure on them is immense.
"Their quality of football, commitment and the sacrifices they have made are to be applauded."
