The Hoops frontman was a second-half substitute as Brendan Rodgers’ men won 2-0 thanks to James Forrest and Moussa Dembele goals.
Griffiths didn’t have any real impact on the game apart from hitting the post with a late chance.
But he made an impact for the supporters after the game when he carried on his record for tying a scarf around a post after a big result.
Griffiths has done it before – against Rangers at Ibrox as well as Linfield at Windsor Park at the beginning of this season.
And now he’s added one Hampden post to it too:

As you can hear from the cheers, the Celtic supporters loved seeing Griffiths and the scarf.
And they’ll continue to enjoy the post-match reaction to the final as the Hoops won the first of what they hope will be a treble again this season.
Today’s result makes it 65 games unbeaten for the champions and it’s going to take a big performance to stop them extending that run and making a play for six major trophies in a row.
