Chew on this. Pop singer Christina Milian is suing mad after a dining experience made her physically ill. The "Dip It Low" singer was seeing and feeling green after feasting on a Kobe beef salad at a Mexicali restaurant in Studio City last week. Halfway into her meal, Milian noticed an odd chewy material in her mouth. She immediately spit it out, only to find it was a piece of ABC gum. Milian ran to the bathroom immediately and puked up her meal. The restaurant may have put her dinner on the house, but they aren't going to get off that easily. Milian is bringing it on -- she's already filed a complaint with the Los Angeles Department of Health. But her beef doesn't with the establishment won't end there. She is currently shopping around for a lawyer. Milian tells TMZ, "The most important thing to me is to make sure my health is okay. Ever since the incident I have not eaten out."
