Tuesday night, Gwyneth Paltrow makes her second appearance on Fox's "Glee." Last time, she arrived at McKinley High as a substitute teacher wanting so badly to pass the student's "cool" test she tossed a few Lindsay Lohan gags into her Spanish lesson. In one of those incredible Hollywood Coincidences, Paltrow's flick "Country Strong" debuted in theaters just a few weeks later.

This time, Paltrow doesn't have a movie to plug, but she is rumored to have a newly signed record contract with Atlanta to put out a country-music album. Those rumors -- also Hollywood Coincidentally -- made the blogosphere one day earlier.

Here's Paltrow -- showing off her range by playing, not a substitute Spanish teacher but a substitute sex-ed teacher -- performing Joan Jett's "Don't You Wanna Touch Me (Oh Yeah)" in black leather, while simultaneously demonstrating to the McKinley kids the finer points of chair dancing. Who said primetime TV isn't educational?
