Simpson cuts ties with Lachey and Mayer

Pop star Jessica Simpson has vowed to cut off communication with her famous exes Nick Lachey and John Mayer - because she is desperate to start a new life with Tony Romo.

The singer has ditched memories of the pair for her latest beau, American football star Romo - changing her cell phone number and e-mail address in an ultimate act of devotion.

She said: "I don't want anybody that's been in my life (before) in my life anymore, and I don't want them to have any way of contacting me... I'm not just dating for fun. I want kids someday. I want a family."
