JLS topless on Marvin Humes's stag do in Las Vegas - pictures
Aston Merrygold, Oritsé Williams and JB Gill, who surprised Humes yesterday by handcuffing him to a dwarf, watched Humes knock back shots by the pool with a group of male friends.
The boys reportedly hired an ex-MI5 operative to plan Humes's stag, which is expected to last over the Bank Holiday weekend.
Humes proposed to The Saturdays singer Rochelle Wiseman during a romantic break over the New Year and the pair are set to tie the knot in July.
