Brinkley also told Williams on Tuesday that she'll be there for the 54-year-old star if she needs "any help" with divorce lawyers.
"I have been through the entire phone book of lawyers, OK?" Brinkley, who has been through four divorces, said with a laugh.
"I will whisper to you during the break," Williams replied. "I have one, but I want to hear what you say."
This interview aired shortly after Williams' ex broke his silence on the couple's split.
"28 years ago I met an amazing woman: Wendy Williams. At the time, I didn't realize that she would not only become my wife, but would also change the face of entertainment and the world," Hunter said in a statement to E! News. "I have dedicated most of our lives to the business empire that is Wendy Williams Hunter, a person that I truly love and respect unconditionally."
In his statement, Hunter also acknowledged infidelity rumors, saying, "I am not proud of my recent actions and take full accountability and apologize to my wife, my family and her amazing fans. I am going through a time of self-reflection and am trying to right some wrongs."
