JLS have arrived in Las Vegas to begin the first leg of Marvin Humes' stag do.
Aston Merrygold, Oritse Williams and Jonathan "JB" Gills were joined by several other friends to help the 27-year-old singer celebrate his last days of freedom before marrying The Saturdays' Rochelle Wiseman.
The boys were seen making their way through McCarron International Airport in Sin City wearing blue customised t-shirts with the words: "Vegas Miami 05.2012" emblazoned on the back.
While it may be a boys only holiday, they certainly packed like women, and were seen struggling with their suitcases. After getting up to no good in Vegas, the group will be heading off to Miami where they will no doubt enjoy the sun, sea and strippers.
Marvin and Rochelle are keeping their wedding date under wraps, but it is rumoured they will be tying the knot this summer.
Will Marvin behave himself?
