Lauren Conrad Instagram shows the beauty in an upgraded do - from dirty blond to a bright platinum hue! And she's looking fabulous!

The reality star posted a snap of her newly dyed hair on Instagram today and caption it, "things are getting real blonde around here..." Could this sudden change be in anticipation of her upcoming wedding date this fall.

For a California girl, the new color totally suits her. To maintain her healthy hair, 'The Hills' alum takes vitamins daily and tries to stray away from heat styling whenever possible. "When possible, I let it air dry," she shared. "Whenever you're putting that much heat on your hair, it's causing damage. So anytime you can skip a step, it helps."

The bride-to-be is gearing up to take that wedded step with her beau William Tell later this year. She also shared some of her wedding preps including her plans to get fit for the big day. The 28-year-old said, "I'm not a huge fan of the gym, to be honest. When I have to go to the gym and put an hour in, I'm just staring at the clock."

She also mentioned that she had no plans of doing a crash diet and that she has no plans to change her current workout routine - which is all about enjoying what California has to offer while staying fit. "I just like getting out, like going on a hike, going on the kayaks, going for a run on the beach. "I really love food. I'm not good at dieting. I try to make smart choices but just eat a little bit less."

In her bachelorette party last month in Mexico, the star was spotted running around in her bikini and she was definitely in great shape. She and her lawyer fiancé got engaged in October and have been dating since Valentine's Day 2012.
