Libel, Defamation or Slander?

My fiance's ex wife of over 10 years has a blog on myspace and she basically trashed him and stated many untruths about him. She included personal information about his finances and what happened in court proceedings. She bashed me also, calling me a gimp when I have had a stroke. Her profile is public and available for viewing for anyone who wishes to. Do any of the above apply?
