They've only just released a song together, but Meek Mill has sparked what could turn into a major rap beef with a series of tweets about superstar Drake.
Meek Mill, who recently released his new album Dreams Worth More Than Money, says Drake didn't write his own verse on their joint song RICO.
Drake has denied the claims, writing "I signed up for greatness. This comes with it" during an Instagram discussion with rapper Hitman Holla.
But in a series of tweets, Philadelphia rapper Meek Mill claimed Drake refused to promote his album because he'd discovered he didn't write his own songs.
