JLS topless on Marvin Humes's stag do in Las Vegas - pictures

JLS were sipping cocktails and soaking up the sun in their swimming trunks as they enjoyed day two of Marvin Humes's stag do in Las Vegas, Nevada.

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.
