WATCH: Tina Fey officially OWNS flesh coloured Spanx

Tina Fey is a complete BOSS but her latest appearance on the last ever David Letterman Show has proven to us exactly just how awesome she is when she literally gave Dave the dress off her back as a parting gift. The best bit? She was sporting a full scaffolding style support-underwear scenario underneath including suctioning-in bodysuit, flesh coloured boulder-holder bra and spanktastic Spanx. Amazing. https://www.youtube.com/watch?t=62&v=2tKhr5Ujbd4
