Cameron Diaz asks Nicole Richie to plan her wedding

Actress Cameron Diaz has reportedly asked her boyfriend Benji Madden's sister-in-law, Nicole Richie, to help her plan her wedding. The 42-year-old 'Other Woman' actress, who recently sparked rumours she is engaged to former Good Charlotte rocker after being spotted showing off a new diamond ring at various events in Los Angeles, has turned to his stylist sister-in-law for advice, reported OK! magazine."Cam has never been a big fan of weddings, so she has no idea where to start," a source said.

Diaz and Richie, who have been friends for years, have been scouting Napa Valley in northern California for the perfect venue, as she hopes to tie the knot next spring. Richie, 33, who is married to Benji's twin brother Joel Madden, approves of the couple's relationship and was the one who got them together.
