Pic: Nick Diaz wears alien mask, trolls Georges St-Pierre

Don't be scared, earthling.

I guess Ultimate Fighting Championship (UFC) jokester Nick Diaz was tuning in for Georges St-Pierre's appearance on Chael Sonnen's recent podcast, and heard all that talk about "Rush" seeing flying saucers over the skies of New Mexico (see those comments here).

And since Kenny Florian already spilled the beans about GSP being deathly afraid of Aliens, Diaz just couldn't help himself.

He could have also worn a Bernard Hopkins mask to the same effect.

Diaz went five rounds with St-Pierre back in 2013 but came up short on the judges' scorecards. He's now going to be tackling another former champion when he climbs back into the cage against Anderson Silva at the UFC 183 pay-per-view (PPV) event on Jan. 31 in Las Vegas, Nevada.

Do they sell a Chris Weidman mask?
