Rihanna Spotted 'Smiling and Giggling' with Pals During Low-Key Bar Outing in Boston

“Pour It Up”!

Rihanna stepped out for a low-key night on the town in Boston on Monday — and returned to the same spot twice Tuesday as well.

The pop star and beauty mogul, 31, hit up Pour House Monday evening with two others, joining a group of friends in the back of the bar at a corner pub table. The group, which arrived around 9 p.m., ordered food and hung out for a couple hours with two bodyguards sitting close by as Rihanna sat facing the back wall.

General manager Brian Peters got a call at home from staff notifying him that the singer had popped in, and he advised the staff: “Just don’t bother her. Treat her like any other customer.”

“She was really, really cool,” Peters told PEOPLE. “She tipped well and everything else.”

After the meal, Rihanna even posed for a quick photo with bar employees. Dressed all in black with pristine white high-top sneakers and her long black hair flowing behind her, the Fenty Beauty founder handed off her styrofoam container of leftovers to a friend before heading back out onto Boylston Street and hopping into a waiting SUV around 11 p.m.

“She smelled unbelievably wonderful,” fellow diner Brian Rene Bergeron told PEOPLE. “She seemed happy, was smiling and giggling as she walked by.”

Rihanna came back to the Pour House on Tuesday for both lunch and dinner, PEOPLE confirmed.

“She said she came back for the food. She said she loves the food. I know she had wings,” Peters said. “She is such a down-to-earth person. She was so respectful and kind to our staff. At the end when she was leaving so she took some time to take pics with our staff, who were starstruck. And we really appreciate her coming in and her support and her patronage.”

This isn’t Rihanna’s first trip to New England. The star has made several surprise appearances in Boston in recent years, mostly with her boyfriend Hassan Jameel, the billionaire heir to the famed Abdul Latif Jameel business dynasty of Saudi Arabia, during his business trips.

Jameel — who has been linked to Rihanna since 2017 — serves as president of the company’s charitable organization, Community Jameel, which frequently partners up with the Massachusetts Institute of Technology in Cambridge.
