Jennifer Lopez Hair: The Singer Rocks Two Outfits With The Same 'Do (PHOTOS)

Even though we mourned the loss of Jennifer Lopez's fabulous "American Idol" style, the singer hasn't seemed to slow her fashion pace since leaving her hosting gig. But, in addition to her outfit choices, it seems that people have been paying close attention to her hair (see: the mild internet frenzy that started after ambiguous photos were released of Jennifer with a possibly-cropped 'do).

Over the weekend, we couldn't help but take notice of the actress' particularly stunning locks. We think we may have even spotted J.Lo's new favorite hairstyle, since the singer decided to wear quite similar looks for two appearances during her tour in Las Vegas. For her pre-concert party, the 43-year-old rocked white hot pants and a matching crop top. Her hair was worn in a sleek half-up, half-down style that harkened back to her "Jenny From The Block" days (the sunglasses didn't hurt either).

Following her performance, Jennifer arrived to the after-party in a bright blue dress. This time, she ditched the shades and wore her hair in a curly teased version of the same style. Obviously, Jennifer looks gorgeous no matter what she does to her hair (ahem), but which iteration of the half-up, half-down look do you prefer? Check out the photos below and tell us what you think.
