Derek Zoolander helps pal Justin Bieber promote his new album

Justin Bieber is pulling out all the stops to promote his upcoming album, Purpose, and even partnered with a really, really, ridiculously good looking male model.

The "Sorry" singer, 21, and Derek Zoolander (Ben Stiller) took to Instagram to pose as twinsies, showing of their best "blue steel" faces.

But the pair didn't stop there. Zoolander also filmed several hilarious promotional videos for Bieber.

"When my good friend Justin Bieber asked me to promote his album, Purpose, I said of course... because I want more Instagram followers," the three-time male model of the year said before striking his famous "blue steel" look. "And I hear it's good."

In another video shared by Bieber, Zoolander claims he doesn't "need to hear Purpose to know it's the best album ever."

"I don't even want to listen it," he adds. "Do I have to?"

Of course, this is not the first time the two have teamed up. Early this summer, Bieber was spotted filming Zoolander 2 in Rome.
