'Glee': Matthew Morrison Reveals an 'Español-Off' With Guest Star Ricky Martin (Video)

[Warning: Mild spoilers.]

Matthew Morrison spilled the beans on how guest star Ricky Martin's Spanish teacher character will affect Will Schuester's standing on Glee.

"My Spanish teaching skills have come into question, so I take night school and Ricky Martin's teaching me Spanish," Morrison tells The Hollywood Reporter at the Fox all-star party on Sunday.

Not the least of which includes the glee club taking part in several days of singing just Latin songs.

"He inspires me to do a Latin Week on Glee," Morrison says. "The kids end up loving him as a teacher so I have to have an Español-off to regain my Spanish teacher pride."

"Will is successful," Morrison reveals before backtracking slightly and giving Martin his due. "Ricky Martin is very successful as well, so we both win."

The actor also hinted at what to expect from the forthcoming Michael Jackson hour, which will feature numbers that are essentially reinterpretations of his music videos.

"I actually didn't get to sing a Michael Jackson song. I was bummed out about it, but at the same breath," Morrison admits, "I didn't have to feel the pressure."

When news that the Glee spinoff was officially dead surfaced Sunday, Morrison admitted to finding out that day and had high hopes that the glee club members graduating will still be around next season. It was reported that Chris Colfer, Lea Michele and Cory Monteith will remain for season 4 with guest star Grant Gustin potentially returning as a regular.

"The people who are graduating will still have some kind of say in the show. They'll still be around in some capacity. The people we started the show with we'll hopefully end the show with," Morrison says.

Will and Emma (Jayma Mays) will reach a pivotal moment in their romance, when he decides to pop the question to the OCD guidance counselor.

Morrison offered this tease: "The actual proposal is probably the coolest, most interesting proposal I've ever seen in my life. It's out of this world."

Glee returns Jan. 17 at 8 p.m. on Fox.
