However you usually treat your friends on their birthdays, it’s probably not quite as well as Jay-Z treats his.

Last week the rapper and hip-hop entrepreneur (hip-hopreneur?) took a buddy out for his birthday and dropped more than $110,000 on dinner and drinks – mostly on drinks – Page Six reports.

Yeah, in some parts of the country you could buy a house for that. But nothing’s too good for a bestie, right?

To celebrate the 50th birthday of his pal Juan “OG” Perez, who is the president of Jay-Z’s sports agency Roc Nation Sports, Jay-Z treated Perez and some other Roc Nation honchos, as well as a few other close friends, to dinner at the high-end Japanese restaurant Zuma, in midtown Manhattan, where they racked up a $13,000 bill, according to Page Six.

Then they trooped uptown to another restaurant, Made in Mexico, where they imbibed $9,000 worth of drinks – including the cognac, D’Ussé, of which he is a part owner.

You’d think that would have been celebration enough, even to mark a milestone half-century, but no. The group, which had then dwindled to only six people, then made a third and exponentially more expensive stop – at a nightclub called Playroom, where they (ahem … he) bought 40 bottles of Ace of Spades Champagne, in which Jay-Z also, as it happens, owns a stake.

No, the music mogul didn’t appear to get a deal on the bottles, despite being a co-owner of the brand; he shelled out $1,200 ea. for 20 bottles of Ace of Spades “Gold” and $2,500 ea. for 20 bottles of Ace of Spades “Rose,” according to a receipt someone who said he was his server posted to social media.

And no, Jay-Z and his pals didn’t drink them all. Page Six reports that the rapper was a generous sharer, handing bottles out to people at other tables.

He was a generous tipper, too: He left $11,100 (15 percent, but who’s counting?) on his $80,035 bar tab.

Here’s hoping the server spends the money on something a little more substantial than really (really) expensive champagne.
