The couple will arrive in the French resort town on June 30, where the party will be held at the exclusive V.I.P. Room for guests including Jamie Foxx and Parker’s brothers, T.J. and Pierre.
“The plan,” one of the club organizers tells PEOPLE, “is for his friends to have one-half of the club and Eva’s party to be on the other side.”
The evening’s entertainment will include performances by hip-hop artists Cut Killer and MC Big Ali from New York City, as well as a DJ session by club owner Jean Roch.
Parker, who has a hit rap record in France, “Balance-toi” (see the video here) and who will be headlining a rap concert in Marseilles on June 29, will also likely take the mic during the night, a friend of his tells PEOPLE.
A rep for Longoria had no comment about the party.
Parker and Longoria are expected to spend one or two days in Saint-Tropez after the bachelor-party weekend before heading to Paris – and the altar.
“Eva arranged all the wedding details,” the Parker pal says. “But Tony has had the idea of having a bachelor party in St. Tropez for a very long time. He first started talking about it last fall.”
Parker told reporters on Thursday that, while he was in charge of food and music for the big event, his fiancée selected the location of the wedding – a 17th-century castle south of Paris. “I don’t care where I’m going to get married,” he said, according to the Associated Press. “It’s a girls’ thing.”
