The pair were spotted for the first time since their nuptials at the Four Seasons hotel in Beverly Hills on Sunday, where they had lunch at the Cabana restaurant. Joining them were Diaz’s new in-laws Nicole Richie and Joel Madden with their two children Harlow, 7, and Sparrow, 5.
“Cameron and Benji looked like newlyweds,” an onlooker tells PEOPLE of the group’s poolside lunch. “They walked around hand-in-hand. They seemed happy too. Cameron looked pretty, but a bit tired. [She was] very casually dressed.”
Diaz, 42, and Madden, 35, wore their wedding rings and made an effort to stay away from photographers, another source says.
“Getting married is the next step when you are totally in love and comfortable with someone,” a source close to Diaz told PEOPLE at the time of the wedding. “Cameron has found true happiness.”
