Happy Belated 21st Birthday, Hayley Williams
"Totally surprised tonight by all my friends," Hayley tweeted along with a photo of her zombie birthday cake.
Pal Taylor Swift was there too. "Just leaving Hayley Williams' surprise b-day party," Taylor tweeted. "Roller skates were worn, Hanson was played. Party! Go Hayley!"
We're not sure what kind of presents Hayley got for her birthday, but judging by this pic, we know she's a fan of Skelanimals. Maybe one of her friends gave her some new duds from the adorable clothing line...

The event was organized by Hayley's boyfriend and New Found Glory guitarist Chad Gilbert.
"We took over the roller rink," Hayley tweeted. "Don't know why I ever have a care in the world with friends like mine. Thanks to everyone that came out tonight! Skate or die, indeed."
