JLS Hit Las Vegas For Marvin's Stag Do - MTV UK

They wore masks of fiancée Rochelle & handcuffed Humes to a dwarf...

JLS have arrived in Las Vegas for bandmate Marvin Humes' bachelor party.

The lads were snapped arriving at McCarron International Airport wearing matching t-shirts with the words 'Vegas Miami 05.2012' written on them, as they prepare to celebrate Marvin's last few weeks of freedom before he marries The Saturdays' singer Rochelle in July.

Upon their arrival to Sin City, the lads took to Twitter to write: "Uh oh... Vegas!" - implying their trip is going to be a bumpy ride, especially for the groom-to-be.

The Beat Again band are thought to have worn masks of Rochelle's face as they kick started the stag proceedings, with a source telling The Daily Star: "A bus pulled up to Las Vegas airport to take Marvin and nine of his closest mates up to their super-expensive hotel.

'When Oritse got on the bus he pulled out masks of Rochelle's face and passed them around for everyone to wear. Oritse then made a speech telling Marv to get used to Rochelle's beautiful face being around 24/7 once they're hitched."

Marvin's bandmates Aston Merrygold, JB Gill and Oritsé Williams have already promised to "cause carnage" on his stag do - with Aston even comparing their adventure to hit movie, The Hangover.

According to The Sun, Merrygold said of their stag party plans: "You heard of the Hangover and Hangover 2? What we are planning will be Hangover 3."

It seems their antics have already begun, with the boys tweeting a snap of Marvin - wearing a t-shirt displaying a woman's body in sexy underwear - handcuffed to a dwarf in the foyer of their hotel.

They also posted a video of Marvin and the dwarf online, as JLS are seen laughing as the dwarf tells Humes: "You do as I say!"

While Marvin is living it up in Vegas, his future wife Rochelle recently revealed that she can't wait to start a family with the 27-year old, telling Cosmopolitan magazine: "I want to have babies in the next five years."
