Jealous Eva's RULES FOR RYAN

The actress has made it clear she's not to be toyed with.

Life in plastic has been fantastic for Ryan Gosling and Margot Robbie. The costars, who play Barbie and Ken in an upcoming live-action movie, have been seen rollerblading down the Venice Beach boardwalk in matching neon outfits and filming a chase scene in Western-inspired outfits. The cast and crew have a ton of fun off-set, too. "They often grab a bite after work, and Margot's even organized a few get-togethers so everyone can bond," a source tells Star.
