If there had been an award for dirtiest look of the night at the 2014 MTV VMAs, it would have gone to Jennifer Lopez. The 45-year-old performer must have forgotten that there were cameras all around the Forum Theater in Southern California, where the show took place. While backstage during a commercial break, Lopez ran into Miley Cyrus. Everything seemed fine, as Lopez hugged the 21-year-old and they exchanged a few words before Lopez continued onward. But as she kept walking, Lopez looked back and gave someone, possibly her handlers, quite a dirty look. It's unclear whether the look was directed at Cyrus.

A dirty look at Miley would seem a bit hypocritical, considering Lopez was just defending the controversial singer earlier this year. She feels protective of Cyrus “because she’s an artist, and she’s being herself in this moment, so how can you ask her not to be?” Lopez told the U.K. version of Glamour magazine in February.

Meanwhile, Lopez is rumored to be dating Casper Smart again. The two were spotted out together in Los Angeles last week, with Smart, 27, driving her white BMW. They just split two months ago, and Lopez obviously did not want to be seen, ducking when she noticed photographers snapping their picture.
