GLEE Sneak Peak! They sing “Yeah!”

For the season finale, we know they’ll be singing some originals, but thanks to MTV News, we also know Usher’s “Yeah!” will be sang!

BUT… it won’t be our McKinley High faves singing the hit, it’ll be an all girl rival group!

It’s definitely VERY good, but will it be good enough to take the National trophy?

Guess we’ll find out on Tuesday!
