His JLS bandmates Aston Merrygold, Oritsé Williams and JB Gill surprised the star by handcuffing him to a entertainer dwarf named '5 Cent'.
Humes was pictured wearing a T-shirt that gives the appearance that he is wearing women's lingerie, reports The Sun.
The boyband were joined by a group of their male friends yesterday (May 2) in the stag -do capital city of the world.
JLS previously revealed that they were planning to hire an ex-MI5 spy for Humes's stag-do weekend.
Humes will marry The Saturdays singer Rochelle Wiseman in July.
The star revealed that he "stuttered and stumbled" while proposing to Wiseman.
