JLS are planning a James-Bond themed stag party for bandmate Marvin Humes.

The 'Proud' hitmakers have enlisted a real-life secret agent to help arrange the send-off for the 26-year-old star - who proposed to The Saturdays' singer Rochelle Wiseman over the festive period - and he will have ''no idea'' about the destination until he arrives in another country.

Aston Merrygold explained: ''The best part about it is that when he leaves the house he'll have no idea where he's going. He'll have his passport and that's it.

''There'll be no airline ticket or anything and we've given the pilot strict instructions to not announce where the plane is going.

''He could be going to the sun or up a mountain. He won't know. The organiser used to work for MI5.''

Marvin - who will tie the knot with Rochelle later this summer - said: ''I have no idea. They won't tell me whether to pack shorts or a coat.''

The boy band - which is also comprised of Oritsé Williams and JB Gill - have joked they ''won't be nice'' to Marvin during the trip, but they plan to get him home safe and sound.

Oritsé added to the Daily Star newspaper: ''Wherever we end up it'll be amazing. If we go to the desert, it will be all good.

''We won't be nice to him. We've know Marvin for all these years - we need to get him back.''
