Nicole Richie work out spandex tights sunglasses nike sweaty cell phone juice

Nicole Richie has less than a month to go until her wedding, and the starlet has been taking her physical fitness quite seriously since we broke the news of her upcoming nuptials.

In fact, this is the third day in a row we've snapped her leaving her Studio City gym all hot and bothered (but with a fabulous pair of shades, natch). Nothing wrong with wanting to look hot in your wedding photo album -- and we have no doubt she will be a beautiful bride.
