The Canadian rapper briefly dated the 'We Found Love' singer during her split with Chris Brown and Drake believes this is one of the reasons he and Chris - who is still on probation for beating Rihanna up in 2009 - are feuding.
Speaking on Elliot Wilson's 'Keep It Thoro' radio show, he said: ''At one point in life, the woman that he loves fell into my lap. I did what a real [man] would do and treated her with respect. She's not up there talking down on me.''
Drake - who famously had a brawl with Chris at New York's W.i.P. Nightclub in June 2012, which left a number of people injured including Eva Longoria's former husband Tony Parker -also blasted Chris' rapping abilities.
He said: ''I don't want to hear that man rap. Nobody wants to hear me rap against him. I really do this. Let him put out that, whatever, 'Project X' or whatever he's working on and I'm going to put out that real s**t for the people.
''Nothing good can come out of that situation.
''His insecurities are the fact that I make better music than him. I'm more poppin' than him.''
