Today marks a major milestone for Kristen Stewart, who's celebrating her 25th birthday. Stewart first tried her hand at acting before she was even a teenager, starring alongside Oscar-winner Jodi Foster in Panic Room at just 11 years old. Since her breakout role in the mega-successful Twilight franchise, Stewart has been lauded for performances in films such as Snow White and the Huntsman, On the Road, and Still Alice, opposite Julianne Moore. Impressive film credits aside, the face of Chanel's eyewear campaign has also set a new record in Hollywood by being the first American actress to be presented with a Cesar Award---the French equivalent of the Oscar---for her work in Cloud of Sils Maria.

In honor of the Stewart's birthday, we're taking a look back at her changing looks through the years, from 2001 to present.
