Jennifer Lopez’s album, Dance Again…The Hits, is up for purchase on iTunes today (which also happens to be her 43rd birthday!), and she kicked off a summer tour with Enrique Iglesias last week. That means, despite having just stepped down from her judging position on American Idol, J.Lo is still in the spotlight, looking fabulous as usual. If you’re like us, you’re a little bit jealous of her thick, gorgeous hair. So many celebrities constantly alter their look, but Lopez sticks with her signature, super-flattering long waves, middle part and face-framing layers. She updates that look once in a while with small changes, such as a lighter color or piecey bangs, proving that the same basic cut can be anything but boring.
