Giants lose, Odell parties on

GIANTS star Odell Beckham Jr. didn’t let Sunday’s crushing loss to the Jets keep him from popping Champagne and partying into Monday morning. The surehanded receiver was spotted with rapper Jadakiss at nightclub Haus — while sources tell us other Giants are keeping partying to a minimum during their losing season.

“He was there until after 3 a.m.,” said a spy. “He came with a group of guys, but not teammates. They ordered several bottles of Champagne and a bottle of Patrón. Girls were trying to come say hi, but he looked bored by them, like it was [a] guys’ night out.”

We’re told Beckham greeted NBA star Draymond Green, whose Golden State Warriors are undefeated. But Beckham was avoiding the Jets’ Devin Smith, who was at Haus celebrating his team’s win. “Obviously neither made an attempt to greet one another,” a source said of the rival wide receivers.

While talented Beckham wasn’t breaking any team rules by being at the club, a nightlife source told us the rest of his team’s been leaving the corks on the bubbly of late. “The Giants have been cracking down on players’ social lives, considering the season they’re having,” said an insider. “Across the board, most of [the players] have slowed down on going out.” But, the source added, “Odell’s their star right now . . . Most will say he’s carrying the team. He feels like he can go out and drink and have fun, because it’s not him who is losing the games.”

A Giants rep denied any team crackdown on players, saying, “[Your] premise is false. I don’t know where Odell has or hasn’t been. Everything else is wrong.”

Meanwhile, even the Giants’ owners are joking about their own nights out. Accepting an award on behalf of his family at the Salvation Army Greater New York Division gala on Tuesday, Giants coowner John Mara said: “I feel more than a little embarrassed to be accepting any kind of award when the [Giants] are 5 and 7,” and, “This is the season of giving, and who’s been more giving this year than the New York Giants?”
