Heading into Malibu, Calif., boutique, Sofia Bananabeat , the newly engaged pair "was super nice and laidback," an onlooker tells PEOPLE. "They [seemed to be] having fun just trying on clothes and hanging out."
At one point, a young girl recognized the duo.
"The little girl told Emily how much she loved her," says the source, adding, "They were so down to earth and took several photos with the young fan."
