Jennifer Lopez grabbed the attention of American Music Awards viewers last night by wearing very little clothing... and by shilling a whole lot for Fiat.

The singer danced and gyrated to a medley of songs during her six-minute set, while also making prominent use of the same car you've undoubtedly seen her endorse in countless commercials over the past few weeks. See for yourself:

The overt, Kim Kardashian-like shill has raised the ire of many celebrities. John Legend, for example, Tweeted in response to the advertisement-based performance: "That had to be the most shameless thing I've ever seen in a performance. I was genuinely shocked."
