Celtic served up another shocker at Rugby Park as Brendan Rodgers men went down 2-1 to Kilmarnock.
It's the second time this season the Scottish champions have succumbed to Derek McInnes' side after the Ayrshire men had bundled them out of the League Cup back in August.
Lightning though struck twice despite Matt O'Riley giving Celtic a first half lead with his ninth goal of the season.
However Kilmarnock came out the traps in the second half with all guns blazing and Nat Phillips put through his own goal on 75 minutes to level the scores.
