Imitation is the sincerest form of flattery; That's definitely the case for Chord Overstreet

The Glee actor may have stolen the spotlight at his costar Matthew Morrison's third annual Halloween/33rd Birthday party at Lure nightclub hosted by Oranum in Hollywood Sunday, Oct. 28.

Overstreet, 23, dressed up as his idol Brad Pitt from his talked-about, spoofed new role as Chanel No. 5 spokesman. The young star wore a long blonde wig and goatee to channel Pitt, 48, from his now infamous fragrance commercial.

"It was spot-on," a source told Us Weekly of Overstreet's costume. "He was getting a lot of attention!"

Pretty Little Liars star Shay Mitchell and Glee star Harry Shum were so impressed by Overstreet's costume they both tweeted a photo of him in costume.

"Happy early birthday to Matt Morrison!" Overstreet tweeted Sunday. "Let's party like it's 1999!" After the party he wrote, "I had the time of my life."

Pitt is Overstreet's favorite actor, and he had the chance to meet him at an after party for the 2012 SAG Awards. "Chord Overstreet met Brad Pitt, his idol, and was ecstatic about it!" a source from inside the event told Us.

And Sunday wasn't the first time Overstreet has dressed up as Pitt. The young actor played Pitt's role in a spoof of Thelma & Louise for the 2011 CMT Music Awards opposite Taylor Swift and Shania Twain.
