Watch: Justin Bieber's awkward onstage striptease for supermodel Lara Stone

Looks like Justin Bieber won't be auditioning for Magic Mike 2 anytime soon.

The 20-year-old hit the Fashion Rocks concert stage and stripped to his boxers in front of supermodel Lara Stone…in the most awkward way possible.

Witness the star tripping over his own trousers while trying to flirt with the married Dutch model in the video above!

Then see how it's done properly in the clip below of Zac Efron getting stripped down by Rita Ora at the MTV Movie Awards below…
