Justin Timberlake plays Napster founder Sean Parker in the new film The Social Network, so for Halloween the real-life Parker, 30, decided to dress as the singer, 29.

Sporting blonde curly hair, Parker hit Heidi Klum's annual Halloween bash Sunday at NYC's Lav, wearing a Timberlake getup.

Parker recently critiqued Timberlake's performance in The Social Network.

"It's a great performance of a character that isn't me," he told

Should Timberlake be nominated for an Academy Award?

"That's a good question," Parker told Us before laughing. "It's not my industry."
