The star had a great time at the beach with her nieces and nephews, cozying up to Madden whenever they had the chance. He blended with her family well and everyone seemed to enjoy themselves together, with Madden becoming part of the family during the brief but meaningful getaway.

The two started dating officially back in May, and according to Us Weekly Madden's sister-in-law Nicole Richie took responsibility for the couple, having introduced them months before. Richie is married to Benji's brother, Joel, and claimed to be a "devoted sister in law", adding "I approve of anything that's going to make Benji happy."

Diaz and Madden certainly seemed happy together during their time in Florida, which would make Richie a pretty good sister in law for the time being.
