The X Factor 2012 live tour hit Ireland this week, as the nine acts taking part performed at The O2 in Dublin city centre.
Fresh from promoting his debut single Seven Nation Army, currently holding on in the iTunes top 10, Marcus Collins joined Amelia Lily, Little Mix, Misha B, Janet Devlin, Craig Colton, Kitty Brucknell, The Risk and Johnny Robinson for a flight over the Irish sea.
And despite having been on the road for two weeks now, performing up to twice a day at venues across the UK, the group showed no let up with their energy packed routines.
Janet Devlin and Craig Colton aside, of course.
The tour will move to Northern Ireland at the end of the week, before travelling back to the mainland for gigs in Birmingham, Brighton and London.
