A late Virgil van Dijk goal secured a 1-0 win that sent the Bhoys top of the SPL on Sunday afternoon.
Celtic are back on top of the SPL.
It's been a long time coming - and Ronny Deila's side haven't made it easy for themselves - but they are finally first.
The Bhoys did things the hard way, of course, coming back from behind to beat Aberdeen 2-1 on Sunday afternoon, with a late Virgil van Dyk winner sealing the result in dramatic circumstances.
Celtic had Scott Brown sent off and Anthony Stokes, who was also booked, could not hide his joy on Twitter after the game.
Massive win today, great desire from the boys until the last minute... Buzzzzzzzing!!— Anthony Stokes (@stoksey10) November 9, 2014
Striker John Guidetti, who didn't actually manage to score for a change, also tweeted - and promised match-winner Van Dijk that he will teach him a new celebration.

Celtic's SPL lead is only based on goal difference, with Inverness Caledonian Thistle level on 26 points with Deila's side. But, whether you are top by 10 points or two goals, first is first, second is nothing.
The Bhoys host Dundee in their first league game back from the international break.
