"She didn't come into the store looking for anything in particular, but she purchased an assortment of bottoms," a source tells PEOPLE, explaining that she left with g-strings, thongs and low-rider bikini undies.
"She was super nice and couldn't have been sweeter to the staff," the source says, adding that she chatted with fiancé Justin Timberlake on her cell phone while she was in the store. "She was ridiculously gorgeous in person."
