Duncan is currently on the road with the boy band, who recently starred on ITV2's The Big Reunion - and now it's half term, Tianie-Finn has been able to watch her daddy perform on stage
Posing backstage after a gig last night (27 October), Duncan took a cute picture of himself and his eight-year-old little girl as they pulled silly faces.
Sharing the snap on Twitter, the singer joked with fans: "Daddy and daughter! She inherited my big tongue! #tourlife #daddy #daughter #blueroulettetour #fam."
Blue are currently travelling around the UK for the 'Roulette' tour and performed in Liverpool last night.
They will enjoy a night off today (28 October) before heading to not-so-sunny Bournemouth for gig tomorrow night.
Meanwhile, the Blue lads - Duncan, Lee Ryan, Antony Costa and Simon Webbe - have recorded a Christmas charity single with their Big Reunion co-stars.
The cover of Wizzard's hit 'Wish It Could Be Christmas Everyday' goes on sale on 15 December and the money raised from sales will go to Text Santa.
