See Lauren Conrad through the years, from 'Laguna Beach' to now

The world was first introduced to Lauren Conrad (aka LC) during her senior year of high school when she joined the cast of "Laguna Beach: The Real Orange County" in 2004. 

In 2005, the reality star stopped by "Total Request Live" to promote the show. For the appearance, she sported the ultimate mid-aughts look of denim Bermuda shorts with an embellished tank top and heels. She added a beaded necklace and chunky bangles to complete the outfit. 

A year later, Conrad opted for old Hollywood glamour when attending the MTV Movie Awards in California. The star paired a simple white dress with strappy sandals and styled her typically pin-straight hair in loose curls for a soft, elegant effect. 

A few months after launching her spinoff series "The Hills," Conrad stepped out at an event in Los Angeles, sporting a belted minidress and simple black heels. 

In 2008, Conrad attended a cocktail party in Washington, D.C. She opted to wear a simple black dress with a sweetheart neckline and subtle ruching throughout the bodice. She wore her hair down in long voluminous curls and added delicate accessories to complete the look. 

Two months before departing "The Hills" in the middle of its fifth season, Conrad attended a party to celebrate the iconic doll Barbie's 50th birthday. The star wore a one-shoulder cocktail dress with contrasting navy and black color-blocking details. 

Conrad greeted fans at a signing for her book "Sweet Little Lies: An L.A. Candy Novel" in 2010. She wore a patterned dress and paired the look with peep-toe pumps and a thin headband. 

In 2011, the star stepped out in West Hollywood, California, wearing a beige dress with a matching bow detail at the waist. She completed the look with a pair of caged sandals. 

The California girl bundled up in New York City in 2012. The star wore a tailored navy jacket paired with opaque black tights and black booties to brave the cold weather. 

Conrad sported a bright blazer for a pre-Golden Globes party in Hollywood. The pop of color served as a bright spot in her muted black and white outfit. 

Conrad stopped by the set of "Extra" in 2014 wearing a sunny coral dress and simple white sandals. 

Conrad showed off a shorter, blonder 'do at a party in 2015. The new style was complemented by her elegant navy minidress and nude sandals. 

Conrad rocked a floral maxi-dress for a polo match in October 2016. She pulled her hair back in an effortless updo to show off the ruffled neckline. 

Just two months after announcing she was expecting her first child with husband William Tell, the star attended the Rebecca Minkoff fashion show in Los Angeles, California. She showed off her growing baby bump in a white off-the-shoulder dress and nude sandals.
