Leigh Griffiths and Stuart Armstrong were on target as Celtic completed the Premiership season as unbeaten champions with a 2-0 victory over Hearts.
Griffiths kick-started the party five minutes after the interval when he headed home a cross from the impressive Patrick Roberts.
And Armstrong netted Celtic's 106th goal of the league campaign with 14 minutes left as Celtic moved to a record 106-point total.
Brendan Rodgers' side secured their 34th win of the league season on a day of celebration at Celtic Park before, during and after the 90 minutes.
As both teams came out, the home fans produced a stadium-wide display in tribute to their Lisbon Lions European Cup-winning team ahead of next Wednesday's 50th anniversary, which included an image of the trophy.
With the league trophy presentation to follow after the game, a sellout home crowd were made to wait for their first celebration of the day.
Celtic, who had Cristian Gamboa in for Mikael Lustig, were restricted to long-range shots in the opening quarter with Kieran Tierney, Griffiths and Callum McGregor all coming close.
Hearts, who gave 19-year-old Jamie Brandon a debut at wing-back, also threatened through free kicks from Alex Tziolis and Bjorn Johnsen, who retained his place after head coach Ian Cathro played down reports of a bust-up with the striker at half-time during the midweek defeat by St Johnstone.
Celtic upped the tempo towards the end of the half but Viktor Noring made a good stop from Dedryck Boyata after a Griffiths corner and Hearts managed to clear after Roberts had turned Aaron Hughes inside and out before firing the ball across goal.
Tom Rogic came on for Gamboa at half-time as Celtic moved to a three-man defence and the extra midfielder quickly made a difference.
Roberts got outside Liam Smith and delivered a right-footed cross for Griffiths to head home from six yards.
The same player came close again after linking up with the same player and Scott Brown hit the outside of the post as Celtic kept up the pressure.
Griffiths turned provider when he got clear down the right and delivered a low cross towards Scott Sinclair at the back post. His ball was cut out but Armstrong was following up and shot into the top corner from 12 yards.
Kolo Toure came off the bench for Celtic and produced a goalmouth clearance to deny Malaury Martin a goal before Johnsen headed against the post from the resulting corner.
Hearts continued their late flurry and Craig Gordon saved Martin's volley at his near post before the whistle blew on an outstanding league campaign for Celtic, who will complete the Treble if they beat Aberdeen in Saturday's Scottish Cup final.
