Saturdays star Rochelle took Alaia-Mai to watch JLS perform their set list on stage for their 'Goodbye' farewell tour, which is their last tour before they split.
In the collage of photos posted on Twitter today, Marvin is seen performing on stage along with his bandmates, Aston Merrygold, JB Gill and Oritsé Williams.
Meanwhile, Rochelle, who looked trendy in a checked wool coat, was seen cuddling little Alaia-Mai.
She may have been inside, but Alaia-Mai was still wrapped up warm in a black coat, grey tights and a beanie hat. Captioning the snap on Twitter, Rochelle said: "Alaia loving watching her Daddy and uncles rehearsing #frontrowbaby."
JLS played the first show on their final tour together in Belfast on Sunday (1 December), and revealed that they were left "speechless" after the concert.
Marvin tweeted: "Last night's show was incredible. I was speechless on that stage at times, it was overwhelming!"
JLS will bow out and go their separate ways at the end of the year after six years together. Their last ever single, 'Billion Lights', is taken from their final album, Goodbye: The Greatest Hits.
