So, how does that work then?
He writes songs in which he graphically describes, to his daughter, the act of killing her mother, and he's allowed to perform them to his heart's content, but she's actually been legally bound not to call him "uncaring" in the public domain?
Tis a very rum do, and no mistake.
'Rapper Eminem and his ex-wife Kim have reached a court agreement to stop insulting each other in public.
The pair, who divorced for the second time last year, pledged to stop trading insults for the sake of their 11-year-old daughter Hailie.
The deal came after the rap star took legal action to stop Kim Mathers making "derogatory, disparaging, inflammatory and otherwise negative comments".
In a recent radio interview, she branded him "uncaring and unfaithful".
According to Ms Mather's lawyer Michael Smith, the order does not prohibit Eminem - real name Marshall Bruce Mathers III - from performing songs that are critical of his former wife. The 34-year-old rapper sung about killing her in his 2000 hit Kim.'
