A$AP Rocky has his family’s quirks on the brain.

The “Peso” rapper recently shared insight into life with his and Rihanna’s sons RZA, 3, and Riot, 21 months, including how they’re developing different personalities as they get older.

“The older one, he stays to himself—he likes his books,” Rocky, 36, told Vogue in an interview published on April 15. Meanwhile, the duo’s younger son fittingly lives up to his name. “He likes to take stuff from his brother so his brother can chase him.”

But he didn’t limit his gushing to his kids. Rocky (real name Rakim Mayers) then showed some love to the Anti singer, 37, describing their romance as “internal, external, infinite, the past, and the future.” And he’s not the only member of the family who can’t get enough of her, as he revealed Rihanna has a sweet bond with his grandmother Cathy.

In fact, she even joined the interview to share her thoughts on her grandson’s partner of 6 years, describing Rihanna as “a down-to-earth person.”
