Actresses NIKKI REED, JULIANNE HOUGH and REBEL WILSON helped BRITTANY SNOW celebrate her 27th birthday in style by attending her big bash in Los Angeles on Saturday (09Mar13).

Snow hosted a glow stick party at the Mack Sennett Studios to mark the occasion, and a number of famous faces turned out to show their support, including her former Pitch Perfect co-stars Wilson, Skylar Astin, Adam Devine, Hana Mae Lee, and Kelley Jakle.

Snow's actor boyfriend Tyler Hoechlin was also in attendance, as were Twilight star Reed and her musician husband Paul MacDonald, Hough, The Vampire Diaries beauty Nina Dobrev, Glee hunk Jonathan Groff, Bruce Willis' daughter Rumer and screenwriter Dustin Lance Black.

And it appears the birthday girl had a good time - in a post on Twitter.com she wrote, "Thank you all for the sweet birthday messages. So honored & grateful."

In addition, Reed posted a handful of candid snapshots from the event and tweeted, "Happy Birthday @Brittanysnow ! Thanks for getting me out of the house, and making me feel hip/cool/young. You know I love to get my dance on..."
