Sydney Sweeney is diving into single life at a New York City dive bar.

The “Euphoria” actress was spotted partying with friends at celebrity-loved Lower East Side watering hole Ray’s Bar Saturday, a spy exclusively tells Page Six.

“Sydney Sweeney brought main character energy,” the spy tells us, adding that she was “holding court” at the owner’s table in the back corner of the venue.

We hear Sweeney, 27, bought the entire bar a round of tequila shots and led a “full-bar sing-along” to Natasha Bedingfield’s hit song “Unwritten,” which was prominently featured in her 2023 comedy “Anyone But You.”

At one point, a bartender announced to the crowd that the “White Lotus” alum was treating everyone to free drinks.

“Sydney Sweeney decided you’re not having enough fun so she bought shots for the bar,” a bartender announced to the crowd, prompting the intimate room to break out in cheers.

Sweeney, dressed in a casual brown leather jacket, reacted to the shout-out by smiling excitedly while seated at the VIP booth with friends.

The “Handmaid’s Tale” starlet hit up the Big Apple just weeks after she attended Jeff Bezos’ $50 million wedding to Lauren Sánchez in Venice, Italy.

A source told Page Six that Sweeney attended the nuptials because, although she is not friends with the billionaire or Sánchez, she is starring in an upcoming potential blockbuster for Bezos’s Amazon MGM Studios.

“[Sweeney] came to pay respects to the ‘boss,’ just like in the old days of Hollywood,” our source confirmed.

The blond beauty was spotted grooving with eligible bachelor Tom Brady on the dance floor at the star-studded reception.

Sweeney is newly single after she and Jonathan Davino called off their engagement in March. They had been together for seven years.

Their split came after Sweeney and her co-star Glen Powell famously sparked romance rumors when they looked flirty on set of their chick flick, “Anyone But You.”

However, Powell later admitted that he played into the gossip to help promote the movie.

Meanwhile, a source claimed that Davino and Sweeney broke up because they had “major issues” in their relationship.
