EXCLUSIVE: LI losers rack up $28,500 in effort to impress rapper Juelz Santana, pay with bogus credit card.

Two wanna-be players looking to catch the eye of a rap star in a celebrity-studded Chelsea nightclub wound up behind bars after they rang up a whopping $28,500 tab on expensive champagne – and tried to pay for it all with a bogus credit card, The Post has learned.

Robsson Depeine, 23, Jeff Sylvain, 24, and five of their friends had reserved a table Monday night in an exclusive section of M2 Ultra Lounge on West 28th Street, according to general manager Dan Devlin.

Rapper Juelz Santana was throwing himself a birthday party with guests that included Hip Hop superstars Lil Kim and Snoop Dogg, Devlin said.

Depeine and Sylvain ordered ten bottles of Moet Nectar Rose at $400 a pop, totaling $4,000, Devlin said. Depeine allegedly presented a valid ID and an AMEX card that initially checked out.

Later that night, the pair ordered thirty more bottles of Moet Nectar Rose, bringing the bill to $16,000, Devlin said.

In an effort to impress Juelz Santana and his entourage, the two Long Island men started sending some of the pricey bubbly over to the musician, who has collaborated with Chris Brown.

"They were certainly trying to impress them," Devlin said.

Depeine then allegedly ordered a nine liter bottle of Veuve Clicquot champagne for $3,500. Then he tried to order another nine liter bottle and a $5,500 twelve liter bottle.

"That’s when one of our managers became suspicious. The purchase was ridiculous and Sylvain introduced a second card with his ID and I knew that’s when there was a problem," Devlin said.

According to a criminal court complaint, Sylvain’s New York State ID was an obvious forgery made out of flimsy material and different coloring. His American Express gift card was doctored using numbers associated with a genuine AMEX credit card.

The club’s staff quickly started taking back the champagne bottles from their table as well as Santana’s, sparking a melee.

When told that the jig was up, Sylvain and Depeine allegedly said, "You got to be kidding me. Are you kidding me?" The two allegedly tried to ditch their buddies and flee the hot spot, but security guards nabbed them.

They are being held on $20,000 bail on charges of grand larceny and criminal possession of a forged instrument.

Joseph Coluccio, the duo's lawyer, denies they even put down a credit card and claims it was the club's fault, saying the crime was pinned on the pair when they couldn't find the real culprits.

"My Clients were invited to a birthday party. There were several people putting down credit cards and ordering pricey bottles of champagne. There was chaos at the end of the night and the bartender realized that there had been fraudulent transactions. The club couldn't find the real person who gave them the credit card, so my clients were wrongfully identified. It's a joke."

Earlier that night, a man sporting a dapper tuxedo coat was busted for a similar crime at M2 after buying a $400 bottle of Moet Nectar Rose and trying to purchase three more, Devlin said.

Devlin said they’re taking proactive measures to counteract credit card fraud, working with the Chelsea’s 10th Precinct and The NYPD’s Identity Fraud Squad.

"The combination has made us very sharp now. People better think twice about coming here (with a stolen credit card) because you are going o go to jail," Devlin said.
