The Bhoys duo took to social media after beating the Dons 1-0.
Scott Brown's second-half winner secured all three points for the Hoops as they extended their lead at the top of the Scottish Premiership to 14 points.
Ronny Deila's men worked hard for the win and Griffiths saw the result as proof of why Celtic are champions, showing pride at their ability to 'dig in' and get the points.
The 24-year-old was recently named the SPFL's Player of the Month for April and, despite the fact Aberdeen prevented him from scoring, this was another good day for the Bhoy.
That's why we're champions, digging in and getting results, #HWGTIAR— leigh griffiths (@Leighgriff09) May 10, 2015
Meanwhile, winger and January signing Stuart Armstrong also celebrated the Aberdeen win on social media, keeping it simple with his message after the game:
Deila was quick to praise match-winner and captain Brown during his post-match press conference, singling the 'brilliant' midfielder out as 'vital' to the Scottish champions' set-up.
Just two games remain of Celtic's league season, with the Hoops due to travel to St Johnstone this Friday, before finishing the campaign off at home to Inverness Caledonian Thistle.
