Forget planking ... Nicki Minaj is starting a new posing trend!

The quirky rapper Tweeted a pic of herself balancing -- in heels! -- inside a refridgerator. "There's definitely a technique behind #fridging barbz," she wrote.

It's not the first pose one would expect, but we have to admit that it makes for one cool pic (all puns intended). Not only that, it also set off a new craze -- tons of her Twitter followers posted pics to the "Super Bass" rapper trying out fridging for themselves.

Nicki is definitely a trendsetter!
