Rihanna was spotted wearing her most conservative outfit yet as she celebrated her grandfather's 86th birthday in New York City on Tuesday.

The Bajan singer wore a Celine long-sleeved turtle neck and long pants matched with nude shoes and a Louis Vuitton box purse, with her hair in a side part.

Rihanna and her Grandpa also rocked birthday hats to the NYC restaurant Nobu.

She posted a photo of her grandfather enjoying his special day on Instagram and captioned ut, "Birthday boy #SkorpioKing."

In another photo of the singer featuring her grandfather, Rihanna's baby cousin is wrapped in her arms.

"We've been leaning on him for generations! #Bravo #86," the caption reads. More recent posts show Rihanna going back to her usual raunchy photos, such as her half-naked posing for Esquire. RiRi made a comeback to Instagram over the Halloween weekend after being off of the social media website for nearly six months. She posted a picture of a cartoon version of herself in red pumps saying, "I'm back B**ches!" while walking a group of dogs on a leash. Each dog's head is replaced with an image; the Instagram logo, the Vevo logo, a Haters! sign, and a dollar bill with her face on it.

Later (before her grandfather's birthday) Rihanna shared loads of pictures of her cover photo shoot for Elle. In one of the photos, she is covered up in a black dress.

"Special thanks to Alex Gonzalez for putting us together for a concept like this..... Elle.com," the caption reads.

And then the social media page goes back to her normal look: topless, with a wedding veil on.

Last May, the singer closed her Instagram after many of her topless and bottomless photos were flagged. She took to Twitter instead to post the pictures she wanted the world to see.

Rihanna is working on her eighth studio album that's scheduled for release next year.
