Cameron Diaz, Husband Benji Madden Celebrate Love With Nicole Richie And Joel Madden; Couples Go On Another Double Date

Newlyweds Cameron Diaz and Benji Madden had a double date with Nicole Richie and Joel Madden during Valentine's Day at the Giorgio Baldi in Santa Monica, California.

A source told Us Weekly that, "Cameron was having a great time, laughing very loudly at everything Benji said."

"She was full of energy and was a chatterbox the entire meal," the article added. "She was whispering to Nicole and laughing, and then looking over at Benji and Joel and laughing. The four of them seem to be super close."

Paparazzi photos show newlyweds Cameron Diaz and Benji Madden wearing matching all-black ensembles, with Joel Madden and wife Nicole Richie, who introduced a splash of color to her outfit by wearing a faux fur coat.

According to the report, Jimmy Kimmel and his wife were also at the restaurant and after a brief chat, the foursome headed off to a secluded corner. Cameron Diaz and husband Benji Madden had a good time with the presence of Nicole Richie and Joel Madden. They stayed at the restaurant for around three hours.

The couple celebrated their wedding at her mansion on Jan. 5. Nicole Richie (who's married to Benji Madden's twin brother Joel), Drew Barrymore, and Cameron Diaz's older sister Chimene Cain were the bridesmaids in the wedding. The former Good Charlotte guitarist also gave the "Sex Tape" actress a note before the vows.

In another report from People, newlyweds Cameron Diaz and Benji Madden seemed to be regulars of the place.

"They didn't even look at the menu and instead ordered their favorites, including ravioli agnolotti with white truffle, lobster and Spigola," the source said.

"Cameron is a regular and looked bella. She seemed excited to be celebrating her first Valentine's Day with Benji," the source added.

Just three days ago, newlyweds Cameron Diaz and Benji Madden were spotted doing groceries at the Whole Foods market.
