Newlyweds Cameron Diaz and Benji Madden have settled into their domestic partnership as they went grocery shopping in Whole Foods market.

"Both were sporting their wedding bands and were each dressed down in their own signature style," said E! News. "Diaz opted to wear boyfriend jeans, ankle boots and a beige sweater, while her new hubby donned a blue plaid button-up, sneakers and leather trousers."

Benji Madden pushed the grocery cart while Cameron Diaz appeared to be pulling it as they walk back to their vehicle. According to the website, the rock star even opened the door for his wife like a true gentleman.

Cameron Diaz was wearing tattered skinny jeans and long-sleeved shirt, while Benji Madden was wearing a blue plaid shirt, leather pants, a pair of sneakers and baseball cap.

"The 'Charlie's Angels' star and the Good Charlotte band member are doing their best to act like a regular married couple with reusable grocery bags, even though they're both worth millions," said Radar Online.

On Tuesday, the newlyweds were shown on kiss cam during the Los Angeles Lakers game. They were gracious enough to lock lips before the thousands in attendance.

"Good thing Madden married such a rich woman, as courtside seats for the Lakers can cost up to $4,000 per ticket!" the tabloid said.

Earlier this month, Cameron Diaz was snapped the first time since her wedding to Benji Madden. The couple had a lunch date with Nicole Richie and husband Joel Madden at the Four Seasons Hotel in Los Angeles.

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.
