The 'She Makes Me Wanna' star giving the thumbs up as the aircraft takes off from Las Vegas.
JLS enjoyed a helicopter ride over the Grand Canyon as Marvin Humes' stag do continued on Thursday (4th June).
The 'She Makes Me Wanna' singer was pictured climbing on board the helicopter at a local Las Vegas airport.
Marvin and the rest of JLS – Aston, Oritse and JB – were all smiles as the fun-filled stag continued into a third day.
Earlier this week, Marvin was pictured handcuffed to an American rapper called 5 Cent following a meal with the rest of the stag party.
After being shown one of the pictures, Marvin's fiancé, The Saturdays' Rochelle Wiseman, wrote on Twitter: "Ye I'm sure his new pal is nice but he can stay there ha."

JLS are understood to have organised an eight-day trip for Marvin, including a visit to Miami, ahead of his marriage to Rochelle later this year.
