Happy Birthday, Kristen Stewart!

What do you get a woman that has everything?

Or, specifically, that has the planet's most swoon-worthy actor in her bed every night.

Such is the dilemma we face today, as Kristen Stewart turns 20. We'd love to get the Twilight Saga star a special present, but let's face: she goes home to Robert Pattinson each evening. Any gift would pale in comparison.

Stewart recently earned solid reviews for her portrayal of Joan Jett in The Runaways, and will likely be making the media rounds often over the next couple months as she helps to promote Eclipse.

So there's pleny of Kristen to come. Which is always a good thing. For now, send in your birthday wishes to the actress and check out the following THG photo montage in her honor:
