ONLY ON RADAR: Brad and Angelina's Supermarket Saturday

Brad Pitt and Angelina Jolie have stayed mum about the rampant breakup rumors but are clearly a united front. The couple was spotted shopping in Oyster Bay together looking "very happy" an onlooker tells RadarOnline.com.

"They were happy, smiling, very friendly," the onlooker at local supermarket Stop & Shop said. "They were happy to give out their autographs and take pictures." When not focused on shopping, the two were often locked in conversation with one another as they made joint decisions and discussed what to buy.

The couple took along daughters Shiloh and Zahara, scooping up a lot of produce and perusing the fish and meat departments.

While the famous mom tried to remain incognito by keeping her glasses on inside, she was quickly recognized due to her A-lister husband. "When I saw Brad and the kids, I knew it was her. She was not wearing very much makeup but was very pretty in person."

The famous family has been renting a house in Long Island, NY, (okay, a $60 million mansion that has two helipads and its own private cove) while Jolie films her spy thriller Salt.
