Nicki Minaj has defended Britney Spears and labelled her ex-husband Kevin Federline as a “coward”.Over recent weeks, singer Federline has claimed that Britney’s sons Jayden James and Sean Preston are not comfortable being around her, and posted a video of Britney arguing with her sons.Appearing on an Amp Livestream, Minaj defended Spears and said Federline was trying to “break [her] down” with his recent posts.“Do you understand what kind of a clown you have to be to be a whole, grown fucking man, and as soon as you see somebody happy and getting married and moving on and being free and feeling good in their own skin, to do the very thing that you know is going to attempt to break them down?” she said.“Only cowards use the media against a famous person who they once loved, they procreated with, they’re being taken care of by, they once were being taken care of by, using the person’s fame as this constant ‘gotcha’ moment… And you think you not gonna have fucking karma from it? You think it’s OK? You think that anybody is gonna feel sorry for you?”Minaj added: “How dare you. How dare you encourage this woman’s children to be a part of your nonsense?” Minaj continued.
