If Gwyneth Paltrow wasn't such a busy A-list actress, we bet Holly Holiday would have a permanent spot as William McKinley High School's resident substitute teacher on Glee.

The lovely Gwyn got a chance to show off her perfectly toned 'bod while educating the Glee kids in '80's work out gear, complete with leg warmers and headband. If only our High School had been this cool!


Paltrow's character also heats things up with the Glee club's hottie teacher Mr. Schuester, aka Matthew Morrison. The pair sang Prince's 1986 hit Kiss in a duet as they performed a sexy tango in a candle-lit room. Awww.

We can't wait for next week's episode!
