The 26-year-old appeared in her first nude shoot on the cover of last month's Australian Rolling Stone magazine. Since then, erotic shots have been published of her posing nude for the latest Pirelli calendar. Kerr is currently dating actor Orlando Bloom and lives with him in Hollywood.
However, she has avoided marriage till now. "He has told her he wants to marry her and will propose again this summer,'' the Daily Telegraph quoted a source close to the couple telling London's Daily Mail.
Bloom apparently has decided to try his luck for the last time. The insider added: "If she says no, he has said it will be over. Orlando discussed marriage with her in New York last year and again in Sydney earlier this year, but she kept saying she was too young.''
