Cameron Diaz and Benji Madden are engaged and reportedly looking to have their wedding in 2015. An insider revealed to Page Six, “Benji is being secretive about the details, but everyone is very excited. They’re trying to keep things private.”

Diaz and Madden had been dating for about seven months before he proposed, and they have confirmed their engagement. Despite his messy habits and her supposed germophobia, it seemed like their relationship was going well. However, new rumors have emerged that the well-known couple is in a dispute over a prenuptial agreement.

Sources close to the situation have revealed to Life & Style magazine that the couple are putting off the wedding planning until they can work out the financial aspects of their eventual union. A source reportedly told the publication, “At stake is Cameron’s $90 million fortune.”

An insider stated that Madden’s net worth is around $20 million, which is small compared to the actress’ income. The source said, “Benji’s pride is wounded. Negotiating about money just shows how much more successful Cam is. He’s concerned that signing a prenup will change their relationship.”

The source added, “Cam shelved all wedding planning until they resolve everything!”

Cameron Diaz and Benji Madden have already moved in together and the Good Charlotte rocker has placed his former home up for sale. As for whether or not the duo plans on having children, it appears that is still up in the air. A source said, “Benji’s friends think he would be an amazing dad. He is already a great uncle to brother Joel’s two kids and he loves kids.”

Life & Style magazine has previously revealed that Diaz and Madden were “at odds” over whether or not to have children together. The magazine revealed that Madden wanted children and Diaz did not and that the rift could eventually affect their relationship altogether.
