Brittany Snow‘s 27th birthday was Pitcher Perfect!
The actress, joined by beau Tyler Hoechlin, rounded up a slew of her former big-screen costars on Saturday to help her celebrate another year.
Skylar Astin, Rebel Wilson, Kelley Jakle, Alexis Knapp and Adam DeVine were among the musical comedy’s actors to attend Snow’s glow-in-the-dark, rave-themed bash at the Mack Sennett Studios in Hollywood.
“There was a deejay, soundstage, fog blowers and all,” a partygoer tells PEOPLE. “Guests danced the night away while tossing their glow sticks in the air. Brittany was in great spirits and mentioned that she wished Anna Kendrick could have been there, but she was at SXSW.”
During the party, which went from 9 p.m. to 3 a.m., guests sipped on drinks by Voli light vodka and watched a reel on the birthday girl’s Love Is Louder charity. And the night didn’t end without a special mini chocolate cake.
