He considered keeping the song with Drake, or giving it to Alicia Keys, but Rihanna's team finally came around “when it was all that she could sing around the house," he said.
"She fought for it," he added. "She said, 'This is my family’s favorite song.'"
PartyNextDoor also opened up about his close relationship with Drake, but kept coy about his friendship with Keeping Up With the Kardashian star Kylie Jenner, which made headlines earlier this year.
"I openly share music with Drake, especially when it’s time for him to have a project," he said, adding that he feels like he has an "older brother I can text anytime, someone who’s super invested because my name is tied into his."
"It's just creatives cooking," he continued of their working relationship. "If he sees something in a song of mine that he feels he can spin around and make better, who am I to say I'm going to selfishly keep it? As a fan of music, that’s wrong."
When asked about casting Jenner as the love interest in his new music video for "Come and See Me," he politely shared, "I'm grateful that really pretty girls like my music, and social media just happens to like really pretty girls."
Jenner and PartyNextDoor sparked romance rumors back in May, after the reality TV star split from her on-again, off-again boyfriend, Tyga. The two have since reconciled.
