Looks like The Peacock’s been bitten by The Green-Eyed Monster.

TMZ says NBC has dumped the singing-dancing cast of TV’s Glee from a scheduled appearance at next month’s Macy’s Thanksgiving Day Parade. Why, you ask? Well, you didn’t hear it from us, but word is the fancy suit and ties over at NBC headquarters are peeved that the upbeat series has proven a ratings winner for FOX, while many of the new additions to its own fall schedule have crashed and burned before November sweeps.

Last month, Glee became the first new fall series to earn a full season pickup.
