Purchasing a round of drinks is one thing. Another example is keeping an entire restaurant’s glasses full throughout the evening.

Champs champ 50 Cent appears to be the type of guy to accomplish the latter.

Page Six reports that a jubilant Fiddy enjoyed lunch at the stylish Si Si in East Hampton over the holiday weekend and spent tens of thousands of dollars on his own Le Chemin du Roi champagne for the Memorial Day celebrations.

50 Cent bought champagne for the whole restaurant when he had lunch in the Hamptons on Sunday.

We’re told he kept glasses topped up with his Le Chemin du Roi champagne.

We’re told the rapper arrived sans reservation and immediately decided to begin sharing the champers.

We’re told the rapper was “in great spirits, surrounded by he Hamptons ladies.” We guess if you get rich rather than die tryin’, you may as well remind everyone about it once in a while.

50 Cent performed for a chic crowd at Surf Lodge in Montauk on Saturday in front of guests including newlyweds Millie Bobby Brown and Jake Bongiovi, Liev Schreiber, restaurateurs Rich Torrisi and Mario Carbone and newly single Sports Illustrated Swimsuit cover model Brooks Nader.

He also performed at Surf Lodge over the holiday weekend.

We’re told that once again the rapper’s bubbly brand was flowing during his surprise set.
