The organisation of Marvin Humes' stag do is to be conducted with military precision - his JLS pals are arranging for a former spy to kidnap him.
A traditional prank may include tying the drunken stag to a tree for a few hours but fellow band member Oritse Williams has met an ex-MI5 agent to organise the covert operation.
Marvin is set to wed The Saturdays singer Rochelle Wiseman in July but his last night of freedom is unlikely to go smoothly for the groom-to-be.
"This guy has told us he will help us get it done in the most discreet way so Marvin will have no idea what will hit him."
JLS singers Aston Merrygold and JB Gill are determined to get Marvin back after he left Oritse red-faced on his birthday last year.
He hired a cougar stripper to surprise him onstage at London's G-A-Y club, where she made Oritse lick whipped cream from her chest.
Oritse said: "After what Marvin did to me on my birthday I am going to make sure his life is hell. It was the most shocking thing that has ever happened to me. I'm not letting it go."
