They costarred with her in the upcoming fantasy film Snow White and the Huntsman, and now Charlize Theron, Chris Hemsworth and Sam Claflin are helping Kristen Stewart celebrate in her 22nd birthday in style.

The trio uploaded separate video cards last Friday to YouTube offering well-wishes to the actress on Monday's special occasion.

Here's what they had to say.

"Kristen Stewart, a little birdie came and told me it was your birthday," proclaimed Charlize. "Dude, happy friggin' birthday. You're awesome. I feel honored to know you. And just keep rockin', man. You're amazing. Mad love."

Theron, who plays the evil Queen Ravenna in the live-action update of the Snow White fable, then blew her a kiss.

As for Hemsworth, the Thor hunk who plays the titular Huntsman, he kept his message short and sweet, as did Claflin.

The sweet missives were the icing on the proverbial cake for K.Stew, especially after the bash her onscreen and offscreen vampire beau, Robert Pattinson, threw her Saturday night at Hollywood hot spot Harvard and Stone replete with a burlesque show and oldies music.

Happy birthday, Kristen!
