Rod Stewart has finally divorced his second wife Rachel Hunter.The divorce papers, which were lodged in Los Angeles Superior Court, showed that the 16-year marriage between the rocker and the supermodel was annulled on November 2 - leaving Rod free to marry his fiancee Penny Lancaster. New Zealand-born Rachel agreed to a contribution from Rod towards a house and trust funds for their two children, daughter Renee, 14, and son Liam,12. Rachel, 37, has slammed Sir Paul McCartney's estranged wife Heather Mills -who is reportedly demanding around $160 million in her divorce settlement - branding her a "gold-digger".She told Britain's The Sun newspaper: "It was never my intention to take Rod to the cleaners. I'd never do what Heather is doing to Paul. I'm not a gold-digger. I earn my own money and I enjoy being independent. "Rod and I have a good relationship now and we are glad we can move on with our lives."Rod, 61, and Penny, 35, celebrated the news by dining at top London restaurant Cipriani. The couple, who have a one-year-old son Alastair, plan to marry next summer. Rod and Rachel married in 1990 following a three-month romance.They separated in 1999 and Rachel filed for divorce in 2003, but then withdrew the papers. Rod filed for divorce last year.
