Steps - Claire Richards, Faye Tozer, H, Lee Latchford-Evans and Lisa Scott-Lee - reunited for the first time in a decade last year and the Sky Living documentary about their feuds, fall-outs and reconciliation was a ratings and critical hit.
The band also benefited from the show's success, announcing a UK arena tour and hitting the No.1 spot in the album charts with their Ultimate Collection.
Steps Reunion returns in the spring and the second run will follow them at dance and vocal classes, costume fittings and on the road as they deal with the pressure of touring the country again as a band.
Sky Living director Jane Johnson said: "We were all hooked on Steps Reunion as we watched the band talk candidly about one of the biggest pop fall-outs in recent history. So we're thrilled to be giving our customers the opportunity to follow them on the next leg of their journey - their huge comeback tour.
"The twists and turns as they balance intense rehearsals with their busy family lives promise to be equally compelling. The most exciting pop comeback of the decade will be played out this spring on Sky Living!"
