JLS and McFly were among the stars who stepped out for the London premiere of Ghost The Musical.
The boy bands were out in full force, along with Girls Aloud's Kimberly Walsh, Popstar To Operastar champion Joe McElderry, Arlene Phillips, Jennifer Ellison and Denise Van Outen at the Piccadilly theatre in the West End.
"Whoever put the Ghost show together needs to get some sort of award! It's a new kind of musical theatre show... can't wait to see it again!" tweeted Marvin Humes after the show.
The production sees ex-Coronation Street actor Richard Fleeshman and Caissie Levy take the lead roles of Sam and Molly, made famous by Patrick Swayze and Demi Moore in the Oscar-winning Hollywood film.
Marvin - who attended with Saturdays girlfriend Rochelle Wiseman - added: "@RFleeshman congrats on your performance in Ghost Richard..the boys and I were truly blown away last night..well done mate..Marvin."
His JLS bandmate JB Gill arrived hand-in-hand with his dancer girlfriend Chloe Tangney, while Aston Merrygold turned up solo.
McFly's Tom Fletcher showed off a new moustache when he arrived with bandmates Danny Jones and Dougie Poynter.
"It's 'Tache: The Sequel! Had fun last night," he joked on Twitter.
The guys continued to be on top form at the musical's after-party at Corinthia Hotel London, where Danny stunned the crowd by giving an impromptu rendition of Bruce Springsteen's My Home Town.
