The 'Take A Chance On Me' star and the band were celebrating their headline show at the O2 Arena at the weekend.
JLS star Marvin Humes was spotted walking hand-in-hand with his fiancé and The Saturdays star Rochelle Wiseman at the band's after party in London following their headline gig at the O2 Arena on Saturday night (21st April).
The 'One Shot' singer was seen sporting a yellow t-shirt and brown blazer complete with red trousers as he lead the 'All Fired Up' singer who looked glamourous in a summery flower patterned dress.
