If you've been keeping up with your favorite stars on Twitter, you've probably noticed a lot of them posting pictures of themselves, 'planking.' While you may not understand this craze, we here at PopCrush decided to share our very favorite plank poses. See Chris Brown, Big Boi, and Usher's kids do their best impressions of a 2 by 4.

  • Chris Brown

    Breezy shows amateurs how it's done. The singer is just dying for you to 'Look at Me Now' in his best plank pose as he looks light as a feather and stiff as a board atop a circular book case. He looks like such a pro, we think his first single off of F.A.M.E. should have been called, 'Plank 3x.'

  • Camryn

    Teen pop sensation Camryn is a newcomer to the music and planking scene, but it doesn't mean she can't join in with the best of 'em. The pint-sized prankster tweeted a picture of her best plank on top of Greyson Chance's piano.

  • Big Boi

    Big Boi has invented our new favorite catchphrase for this craze, playing off the UGK song title 'International Players Anthem.' The OutKast star tweeted, "#planking " international Planka's " # weoutchea." Hit single in the making? We think so.

  • Redfoo of LMFAO

    And the award for MDP (Most Dangerous Planker) goes to Redfoo from LMFAO! One half of the 'Party Rock' duo flaunted his best pose in oncoming traffic, tweeting simply "My first plank... #sorryforpartyrocking #planking." We guess he's a member of the, 'do as I say, not as I plank' school of thinking.

  • Usher's Kids

    It's a family affair over at the Raymond household with Usher's two boys Usher (Jr.) and Naviyd planking 'round the family piano. Maybe these two little guys will grow up to have hit songs entitled, 'Plank in This Club' or perhaps, 'You Make Me Wanna Plank.'

  • Ludacris' Friend

    Luda's friend makes a great play on words when he planks in front of red neon sign that reads, 'Straits'. Luda made sure to give props to his boy when he tweeted this pic saying, "The new king of planking! @themallyg killin em!!! Lol." We hope Luda comes out with a 'Plankin' All Over the World' series of Twitpics!

  • Afrojack

    Last, but certainly not least, we have producer Afrojack, plankin' away in a mysterious hallway. We love the simplicity of his plank pose. Sometimes less, really is, more. He collaborated on 'Run the World (Girls)' with Beyonce, maybe they can work on a plank duet together in the future.
