Snow White and the Huntsman Cast to Kristen Stewart: Happy Birthday!

Snow White and the Huntsman stars Charlize Theron, Chris Hemsworth and Sam Claflin are helping celebrate Kristen Stewart's 22nd birthday in style.

The trio, in their amazing accents, uploaded separate video cards to offer well-wishes to the actress, who plays Snow White, on the special occasion.

"Kristen Stewart, a little birdie came and told me it was your birthday," proclaimed Theron. "Dude, happy friggin' birthday. You're awesome."

"I feel honored to know you. Just keep rockin', man. You're amazing. Mad love."

Theron, who plays the evil Queen, then blew her a kiss. As for Hemsworth and Claflin, they kept it short and sweet ... but man those guys are cool.
