Kristen Stewart Style: 'Twilight' Star Turns 23 (PHOTOS)

Not even movie vampires are immortal.

"Twilight" star Kristen Stewart celebrates her 23rd birthday on April 9 and we can bet she will probably be wearing her trademark Converse sneakers, an old grey-tee tied up around the waist, skinny jeans and messy hair.

Not that boyfriend, (and fellow "Twilight" vampire) Robert Pattinson will mind!

The highest-paid movie couple were recently spotted in Los Angeles being touchy-feely, putting rumours that the couple have split to rest. (The couple briefly broke up last summer when Kristen's affair with her "Snow White and the Huntsman" director Rupert Sanders was revealed.)

Not that Kristen is spending all her time with Pattinson; the "On The Road" star was recently at the Kids' Choice Awards hanging out with friends (and on Katy Perry's lap) looking ever-so-chic in a polka dot outfit.

Kristen cleans herself up nice when she's not hiding under a baseball cap, right?

So, in honour of her birthday, we take a look at her style evolution.
