Rihanna and A$AP Rocky threw a party for their eldest son's fourth birthday.
Rihanna and A$AP Rocky threw a party in New York City to celebrate their eldest son RZA's (pronounced "Reeza") fourth birthday. The couple was photographed leaving The Sloomoo Institute, an interactive slime museum where the celebration was held.
According to a Page Six source, the parents rented out the venue for the entire evening for the birthday boy and his younger children, two-year-old Riot and eight-month-old Rocky. There were no other celebrities among the guests; the celebration was held in a small circle of close friends and family. 
Rihanna, 38, opted for a loose white T-shirt and cream sweatpants for her vacation, accessorizing with white ballet flats, gold jewelry, a Christian Dior bag, and sunglasses. A$AP Rocky, 37, opted for a sand-colored Burberry trench coat, a gray T-shirt, and jeans, adding a Chanel bag.
Earlier, Rihanna and A$AP Rocky attended the Met Gala. Shortly before, the singer flew to Mumbai and attended a gala dinner hosted by Asia's wealthiest Ambani family.
As a reminder, Rihanna and rapper A$AP Rocky (real name Rakim Mayers) have been together for about five years. Rumor has it that the couple married long ago, but they don't want to publicize it. Despite the recent birth of their youngest child, online speculation suggests the singer is already pregnant again.
