She may be single but she's definitely looking fabulous.

Just after Gwyneth Paltrow made the announcement that she and hubby Chris Martin were making a "conscious uncoupling," fans were privy to a peek at her upcoming appearance on FOX's hit musical comedy, Glee -- and it's disco fabulous!

In the clip, the newly single sistah reprises her recurring role as unruly substitute teacher Holly Holiday. True to the wild character's form, Holiday invades Will Schuester's class and impersonates animal husbandry icon Temple Grandin in a big way. In no time, the leggy blonde is whipping of her wig, singing and strutting around the classroom to Eddie Murphy's 1985 "Party All the Time." A quick change later, the 41-year-old is walking it out through the halls of William McKinley high in a glitzy disco outfit, consisting of shimmery halter top and high wasted dance pants. Damn does this mother of two look good!

And while things may be going well for the Oscar winner on the small screen, it's clear things aren't so fab off screen. On Tuesday, the duo put out a statement on Gwynnie's website Goop, saying, "It is with hearts full of sadness that we have decided to separate."

Glee airs on FOX on Tuesdays at 8pm PST.
