Anna Nicole Smith has attacked Jessica Simpson and warned her the media will soon turn on her.
In a venomous column in the National Enquirer, the blonde bombshell also challenges the singer-turned-actress to take an IQ test on TV to prove she has the high IQ she claims to possess.
Smith writes: "I heard that Jessica Simpson is running her mouth again about not wanting to be compared to me. Well I've got news for you, honey - the feeling is mutual.
"Let's see how you react when the media turns on you - and they will! You'll be lucky if they compare you to Pam Anderson!
"Oh, and what's this about you supposedly having an IQ of 160? Please! You should take an IQ test on live TV."
