Rihanna asked a restaurant to stay open after closing so she could enjoy a late night dinner with her friends.

To return the favor, he helped the staff clean up at the end of the evening.

As Page Six reports, Rihanna and six of her friends ate caviar and sashimi at New York City's Michelin-starred Caviar Russe restaurant until 2:00 a.m. on September 1st.

To thank the restaurant for staying open, Rihanna helped the staff clean up and push the bar stools back into place after staying so late."

Rihanna was dressed casually for her outing in New York. She wore baggy jeans, an oversized No Limit Records sweatshirt, a pair of lace-up heels and Tiffany & Co. jewelry.

The 34-year-old singer has been hitting the streets of New York quite a bit lately, often with her partner A$AP Rocky, who hails from Harlem.

Last week, the two artists were spotted at New York nightlife 'king' Richie Akiva's new hotspot members club 'The Ned' and looked 'relaxed and definitely happy'.

Rihanna and A$AP Rocky welcomed their first child last May, a baby boy, whose name has not been revealed.

Since having their son, they have kept a relatively low profile.

A source told Us Weekly: “They rarely leave their baby's side. They don't talk much about their newborn due to their concern for his safety and really want to keep him out of the public eye for now."

"They both feel truly blessed and couldn't be happier," she added.

In July, Rihanna was named America's youngest self-made female billionaire.

While she has built a business empire with cosmetics company Fenty Beauty and underwear brand Savage X Fenty, Rihanna has not forgotten her humble roots in Barbados and donates significant amounts to charity.

Earlier this year, he donated $15 million to 18 organizations fighting climate change in the United States and the Caribbean.
