The Cameron Diaz and Benji Madden wedding rumors have surfaced once again as one tabloid suggested that the "Sex Tape" star reportedly asked Nicole Ritchie to plan the whole ceremony. Meanwhile, another report claimed that the ex-guitarist of Good Charlotte hates his girlfriend's diet.

The OK! Magazine, as shared by Heat World, reignited the Cameron Diaz and Benji Madden wedding rumors when it reported that the 42-year-old requested Lionel Ritchie's daughter to take care of the preparations.

Nicole Ritchie is married to Joel Madden, Benji's twin brother.

"Cam has never been a big fan of weddings, so she has no idea where to start," a source told the magazine.

Allegedly, Nicole Ritchie already scouted the Napa Valley in California as one of the potential locations for Cameron Diaz and Benji Madden's wedding.

Meanwhile, in another article from the magazine, as reported by Belfast Telegraph, Cameron Diaz has been encouraging him to live a healthier lifestyle and that means changing the way he eats.

"She's got him a trainer and put him on a gluten-free diet. [He] hates it," another source told the magazine.

"[Cameron] has banned him from indulging in his favourite junk food. It's a huge adjustment for him as he loves his burgers when he's recording in the studio, but he loves Cameron more," the insider added.

Even if he hates it, however, he acknowledges that he lost weight because of it.

Earlier, Us Magazine, suggested that Cameron Diaz and Benji Madden are already engaged after she wore a gold ring and diamond band on her finger during the Academy's Hollywood Costume luncheon.

"The 'Sex Tape' actress' new bling has sparked rumors of a possible engagement to boyfriend Benji Madden," it said.

There's no confirmation yet on whether Benji Madden, 35, did propose to Cameron Diaz, her mom is reportedly ecstatic.

"Billie has been gushing about Cameron's new relationship. She absolutely loves Benji and she hopes this is the man her daughter will finally settle down with," a source told the magazine.
