McGee, who earlier this month openly apologized to James's wife, Sandra Bullock, is scheduled to sign autographs, pose for photos and dance topless at Vegas's Deja Vu Showgirls club on April 23.
"We're just cashing in on her celebrity right now," Deju Vu advertising and marketing director Larry Beard tells PEOPLE.
McGee's payment by the club, in addition to tips she might receive, will be $5,000 – money that Beard expects to recoup and then some, given her notoriety as "the other woman."
"There's actually a group of tattoo enthusiasts that are all going to show up," Beard says. "I'm getting a lot of response for it. It should be a pretty big event. She's a dancer. This is right down her alley."
Adds Beard: "Good publicity, bad publicity, it's all publicity to me," he said. "I mean, I don't expect Sandra Bullock to show up."
