After his divorce, he dated Susan Kuronen (she later changed her last name to Ruusunen). In February 2007, Kuronen released a tell-all book "The Prime Minister's Bride", which actually boosted the prime minister's popularity with the public. Tens of thousands of Finns signed an online petition against the book and some bookstores refused to put it on the shelf. Vanhanen sued the book's publisher (but not Kuronen) for invasion of privacy in March 2007, following the March elections. In 2010 the Supreme Court of Finland upheld the privacy violation conviction against Susan Ruusunen and her publisher.
