Westlife thanked their fans being like the fourth member of the band on Saturday night as they performed as a trio for the second night in succession in Newcastle.
The band arrives on Tyneside as a four on Friday night but, after being rather late on stage at the Utilita Arena, Shane Filan, Nicky Byrne and Kian Egan weren't joined by Mark, with him putting out a statement on Instagram right before the show was due to start.
The singer wrote: ""I'm so sorry to tell you I won't be able to join the boys on stage tonight in Newcastle.
