R&B singer Ne-Yo and a group friends have reportedly racked up a $800 bill in food and drinks at Negril restaurant located in the West Village in New York City ... then later bailed without paying.

According to the NYDailynews, Ne-Yo took a group of girls, some guys and his bodyguard to the upscale eatery to have lunch earlier this month. But the Grammy-Award winner wasn't balling that day as he then left the restaurant without paying the tab. A source told the site:

“We had a Monday Night Football thing, the Giants were in, too, and Ne-Yo came in with [road manager] Jayvon Smith, a group of girls, some guys and a bodyguard,” one eyewitness tells Confidenti@l.

“He was ordering all this stuff and he kept asking people what they want, and kept the drinks coming.” Even though the waitress on Ne-Yo duty was “run ragged” by his needy group, our tipster tells us she was overly helpful and enthusiastic toward the singer and his crew.

“The waitress was really sweet, she even helped his bodyguard, who sat at the bar while the group ate,” says the source. “She’s smiling like she’s going to get a good tip and she ends up looking for him after no one paid the bill.” According to our source, Ne-Yo’s server took the check over to his table when the group looked like they were about to leave — only to have them start arguing over who would foot the bill.

“She asked specifically, ‘Is it okay if everyone is on your check?’ and he said, ‘Yes,” says our source. “She hands it to him, he hands it to his manager, his manager hands it to another guy in the group, who hands it back to Ne-Yo.”

According to the report, someone in the group “promised they’d be back tomorrow to take care of the tab,” but the bill still remains unpaid.
