Diageo and Bartle Bogle Hegarty (BBH) have ended their collaboration, with the British drinks giant to handle Baileys and Gordons activity in-house.
BBH, the British advertising agency, was associated with Diageo for 15-years.
Made by Gilbeys of Ireland, Baileys Irish Cream is an Irish whiskey and cream based liqueur with 17% ABV.
Gordon's, considered as the worlds best selling London dry gin, was first produced in 1769 in Scotland.
According to the companies the separation is "mutual" and there will be no pitches for the accounts for one year.
Diageo chief marketing officer Syl Saller was quoted by The Drum as saying: "BBH has always challenged us in the right way and we have always appreciated their candour, strategic leadership and creative brilliance.
"Johnnie Walker's growth trajectory was transformed by the 'Keep Walking' campaign and we are enormously proud of the work on Gordon's and Baileys. BBH has tremendous people who have put their heart and soul into creating great work for Diageo, and we are grateful to each and every one of them."
This follows Diageo crediting cuts to its marketing for offsetting following sales in the back end of 2014.
