Luis Palma struck a late winner as champions Celtic twice came from behind to see off St Mirren 3-2 on the final day of the Scottish Premiership season.
It was a day of celebrations at Celtic Park for Brendan Rodgers side, who wrapped up their third successive domestic title in midweek.
However, St Mirren threatened to spoil the party when Mark O Hara fired them in front after just seven minutes.
Top scorer Matt O Riley equalised for the hosts in the 21st minute, but they fell behind again just five minutes later when O Hara doubled his tally from the penalty spot after Stephen Welsh fouled Toyosi Olusanya.
Kyogo Furuhashi levelled for Celtic before half-time, and the Hoops completed the turnaround with Palma scored the winner with four minutes remaining.

Rodgers side finished eight points clear of second-place Rangers, who were held to a 3-3 draw by Hearts.
Despite falling behind to Lawrence Shankland s strike, goals from Ross McCausland, Todd Cantwell and Fabio Silva seemingly had the visitors on course for a comfortable win at Tynecastle.
However, there was to be a late twist with Dexter Lembikisa pulling a goal back in the 82nd minute, before Kyosuke Tagawa struck deep into stoppage time to rescue a point for the hosts.
There was also nothing to separate Dundee and Kilmarnock, who drew 1-1 in the other match on the final day.
Luke McCowan cancelled out Gary Mackay-Steven s earlier effort, though the Dundee captain squandered a glorious opportunity to complete the turnaround when he missed a penalty two minutes from time.
