Rihanna celebrates mom’s 52nd birthday in New York

She was dressed to the nines — and it’s not even her birthday.

Rihanna was spotted celebrating her mom Monica Braithwaite’s birthday in New York on Monday night, decked out in chic sheer pants, a leather jacket and studded gloves.

Just a day after quietly attending an anti-Asian hate rally in Manhattan, the pop superstar attended the family gathering in honor of Monica turning 52.

We’re told Rihanna, 33, arrived fashionably late to the dinner at hotspot Pastis around 10 p.m.

In addition to her Fendi purse, the “Where Have You Been” singer was photographed holding a birthday gift bag for the occasion.

A source told us the Fenty Beauty Founder was “giddy” and “laughing” as she entered the venue.

Her grandparents, Lionel and Clara Braithwaite, were the first to arrive at Pastis. Monica showed up 30 minutes later with Rihanna’s brother by her side. Rihanna arrived last.

The superstar’s boyfriend, A$AP Rocky, was noticeably missing from the gathering, but we’re told he was out of town. The “Fashion Killa” rapper was spotted departing for London at JFK Airport on Saturday.

Reps for Rihanna and A$AP did not immediately return our requests for comment.
