"The fireworks were awesome and she had a great birthday celebration," her rep tells E! News. "A fire truck was there for standard safety procedures."
Judging from the pics, she certainly had a good time with castmates, including Emma Roberts and Neve Campbell, as she danced with Oompa-Loompas from Jeff Beacher's Madhouse and a got a dolphin-shaped cake made especially for her.
And given that Hayden's of drinking age, she didn't waste any time taking shots with her mom Lesley, Hollywood Life reports.
Hmm...Is this partying mother-daughter duo the new Dina and Lindsay?
As for her Russian boxer boyfriend, Wladimir Klitschko, he wasn't there but had a good excuse. According to TMZ, he's in training camp for an upcoming match in Germany.
