Rihanna and A$AP Rocky's eldest son is growing up!

It seems like yesterday when RZA was born, now he's celebrating another birthday. On Monday (May 13), his parents celebrated his second trip around the sun with a major bash with all the bells and whistles, according to PEOPLE.

The "D.M.B." rapper took to Instagram with sweet photos of the foursome, highlighting fun family moments. In the first snap, RiRi holds baby Riot while the proud dad holds RZA upside down.

"HAPPIEST BIRTHDAY 2 MY 1st BORN BABY BOY RZA," A$AP penned in the post's caption followed by a red heart emoji.

The next photo shows RZA smiling while holding a green toy as Dad gives him a smooch.

One of the cutest frames captures the singer and rapper smiling at the camera while each holds one of their sons.

On Saturday (May 11), the parents hosted a private party for RZA's birthday at Color Factory in New York City.

Producer President Hitkidd and makeup artist Jasmine B. Cook, or “Jazzy B.” posted highlights from the event, including adorable cutouts of RZA'a face in a variety of poses and a sweet video of the family of four taking photos while sitting on a pink bench as pink confetti fills the air.
