Phil Collins and his bandmates last played together in 2007
They haven't played together since the Live Earth concert in 2007, but Genesis are reforming for a tour later this year.
Phil Collins, Mike Rutherford and Tony Banks will be joined by Nicholas Collins (Phil's son) on drums and Daryl Stuermer on guitar and bass.
The news was revealed on Zoe Ball's BBC Radio breakfast show this morning.
The Last Domino? tour will begin at Dublin's 3Arena on November 16th before travelling to Belfast on November 19th and then on to the UK.
Founding member Peter Gabriel, who left the band in 1975, will not be taking part.
Phil Collins - who originally announced his retirement in 2002 due to health reasons - embarked upon his own comeback tour in 2017. He has had various surgeries to cope with his drumming-related injuries over the years, which explains why his son Nicholas is taking his place behind the kit.
Tickets for both dates go on general sale this Monday at 9am, but there are pre-sales for 3 customers (Thursday at 9am) and an MCD pre-sale (Friday at 9am).
