The publication reported on behalf of US Weekly that the couple bought a $6.7 million four-bedroom home which "is just a few doors down from Cameron's." The two reportedly moved in earlier this month.

The couples are apparently extremely close and Richie recently admitted she set Diaz up with her brother-in-law only seven months before they wed.

"Yes. I'm going to take responsibility for everything! I approve of anything that's going to make Benji happy. I am a devoted sister-in-law. I'm happy for anyone who is happy, and I want everyone to be surrounded with love," Richie said.

The report also said that Diaz is just as devoted as an aunt to her new seven-year-old niece Harlow and five-year-old nephew Sparrow.

"She's more determined to have a baby, seeing how wonderful Nicole's family life is. She's inspired by Nicole on many levels," a source allegedly said.
