American Rapper Kendrick Lamar and Canadiain Rapper Drake have both released new diss tracks as the feud between them intensifies with brutal verses dragging in their families.
Lamar earlier this week replied to two tracks by Drake with Euphoria - where he called the Canadian rapper a "scam artist.
Drake responded with Family Matters, hitting back: "Why you never hold your son and tell him to say cheese. We could have left the kids out of this don't blame me."
The lyrics seem to be a response to Lamar questioning his abilities as a father on Euphoria.
In his latest release, Drake - the world's most-streamed hip-hop artist - also seemed to suggest one of Lamar's children had been fathered by someone else.
Kendrick Lamar got just as personal in his almost immediate response, Meet the Grahams, which mentions Drake's son Adonis, as well as his mother and father - Sandra and Dennis Graham.
"Dear Adonis, I'm sorry that that man is your father. Let me be honest, it takes a man to be a man, your dad is not responsive," Lamar states.
Drake and Lamar - whose fourth album won a Pulitzer Prize - have for years been exchanging thinly veiled barbs.
