Is it just us, or is it hard for anyone to believe that Jennifer Lopez turns 45 today? Let's take a look at the star's best fashion moments over the years. First up, we've got a sparkling silver Emilio Pucci mini from the 2011 Grammys that incorporates Lopez's three main style staples—super short, super sparkly and ridiculously sexy. Now add on a few yards of fabric, and you've got J.Lo's still sexy Zuhair Murad princess gown from the 2010 Met Gala.
