The role of Neil Patrick Harris has not just been confirmed.

It's now been revealed!

The How I Met Your Mother star will come aboard the Fox comedy in May as Bryan Adam, a high school glee club nemesis of Will’s. He's now a board member at William McKinley High School.

“Flashback scenes will show Bryan picking up girls and getting all the cool solos,” a source told Entertainment Weekly, “while Will sits off in the sidelines.”

Why do these rivals meet again? Adam announces his plans to cut the arts programs at the school.

“Show choir ruined his life, made him feel he could be a star, but all he could do is book Carnival cruises,” said insider. “Now he wants vengeance."

And we want this episode to arrive as quickly as humanly possible.
