Lea Michele and Gwyneth Paltrow Bring All that Jazz to Glee with Chicago's 'Nowadays'

With Mr. Schuester (Matthew Morrison) under the weather this week on Glee, it was up to substitute teacher Holly Holliday (guest star Gwyneth Paltrow) to lead the teens of New Directions in their weekly song and dance routines. While we hate to see Mr. Schue sidelined, it's great to welcome such a fun-loving adult mentor to the club. Though Rachel (Lea Michele) was most definitely not a fan of Holly at first, the resident glee club diva soon warmed up to the substitute and embraced her idea of letting loose. For their duet, Rachel and Holly channeled Broadway's most notorious sparring divas: Roxie Hart and Velma Kelly of Chicago. The ladies began with the show's closing number "Nowadays" before breaking out some sensational jazz moves for a sizzling "Hot Honey Rag." Watch the razzle dazzle below.
