Actress Cameron Diaz’s husband and musician Benji Madden has sued a designer for $500,000 for “improperly remodelling” his house.

The Good Charlotte band member says he made a deal with Ryan Silverman and The Wooden Palate in the spring of 2015 to remodel his spare bedroom, kitchen, laundry room and deck and wine cellar.

According to the documents, workers finished the project in October 2016 — at which point Madden had spent over $478,509 — but he said the job “was done improperly and would have to be redone”, reports

In the suit, Madden says the custom-built doors for the wine cellar had to be repaired, along with other defects, to the tune of an extra $78,000.

Madden wants more than $500,000 back in damages and a big refund plus his legal fees.
