Last week, Luann de Lesseps announced that she’s now “drinking responsibly” after completing her probation, which banned her from boozing.

Perhaps the reality star was celebrating her newfound non-sobriety last Saturday when a Page Six spy spotted her and a pal leaving Lulu in Sag Harbor after what appeared to be an extremely responsible boozy meal. In fact, we’re told the pair were so absolutely responsible that they couldn’t get it together enough to order an Uber, and a stranger had to give them a ride home.

But the “Real Housewives of New York City” star told us, “I was having dinner with a friend. When we ordered an Uber to go home, it said it would be 18 minutes.” She added, “My neighbor was just finishing dinner too, and she was gracious enough to offer me a ride home. I love my neighbors!” She didn’t deny she’d been boozing — just that she’d been too wasted to order an Uber.

The cabaret star finished her probation — stemming from her 2017 arrest for disorderly conduct — in August.

Last week, she told People, “I’ve learned a great deal about myself, and I’m in a very good place and finally back in the driver’s seat.” She added, “I’m toasting to a happy new year ahead!”
