Credit: FOX

The 100th episode of Glee hits the airwaves this Tuesday, and the occasion is being celebrated with a cover of Pharrell Williams' Oscar-nominated hit, "Happy," from the soundtrack to Despicable Me 2. Gwyneth Paltrow will be performing the tune on the hotly-anticipated episode, aptly titled "100".

The episode not only features Paltrow reprising her Emmy-winning role as substitute teacher Holly Holliday, the hour will also feature appearances by alums Kristin Chenoweth and Chace Crawford. It's kind of crazy to think it's been 100 episodes, but then, it's no less weird than the notion that Glee is one of the most successful Billboard properties of all-time. The upcoming album Glee: The Music Celebrating 100 Episodes, on which “Happy” will be featured, is expected to do solid business, so if you're not yet sick of "Happy," you now have something else to look forward to! Until then, you can listen to Gwyneth Paltrow's cover of "Happy" below via Entertainment Weekly:
