Bar RafaeliSupermodel Bar Refaeli is sick of seeing stick-thin girls starving themselves in hopes of landing a runway modeling gig, so she decided to take a stand and rant to her Twitter fans.

According to HollywoodLife, she tweeted, "I get so sad when I see 15-year-old pale extremely skinny models at the agency looking all shaky and hungry ... when will it end?!?!?"

The 5-foot-9-inch supermodel is represented by One Management in NYC.
