The group started their nationwide 'The Ultimate Tour' at Belfast's Odyssey Arena last night (April 2) and performed some of their most popular hits.
However, the band also played a variety of covers throughout the show, including a mash-up of Lady GaGa's 'Judas' and their own version of Kylie Minogue's 'Better The Devil You Know'.
Lee Latchford-Evans and Faye Tozer performed Maroon 5's 'Moves Like Jagger' and Rihanna's 'S&M' as part of a medley, while Lisa Scott-Lee mashed together her own solo hit 'Lately' with Chris Brown's 'Beautiful People'.
Steps also performed their classic takes on 'Tragedy' and Abba's 'Dancing Queen', along with their popular singles 'One For Sorrow' and 'Deeper Shade of Blue'.
The group will move on to Dublin's O2 Arena tonight (April 3), before returning to the UK for their show at Liverpool's Echo Arena on April 4.
Behind-the-scenes footage of Steps' preparations and travelling with the tour will be aired as part of their second documentary series on Sky Living later this year.
